AN INSIGHT INTO NZ’S UNIQUE MARINE ENGINES – Part Four

Todays WW story follows on from earlier stories – link below to Part One,Two and Three 
As per pervious stories in the series the content has been pulled together by Ken Ricketts and ‘polished’ by Patrica and Ken’s daughter Corinne Pettersen. As always we have endeavoured to be as factual as possible but there will always by matters others will either know more about or be able to correct errors – so woodys do not hold back on commenting.

PAXMAN V12 VALENTA RP200 – 3030HP MARINE DIESEL ENGINES

PAXMAN RP200 3033hp V12 MARINE DIESEL ENGINE AS IN THE RNZNs 4 COASTAL PATROL CRAFT FROM 1975-1990

 RNZN COASTAL PATROL VESSEL TAUPO, in 1975

 I’m only aware of four boats that used PAXMAN MARINE DIESEL ENGINES. They were all replacement vessels for the WWII HDML and Fairmiles, with the first, the Taupo, going into service on 29th July 1975. The second, the Hawea, arrived shortly afterwards, followed by the last two, the Rotoiti and Pukaki, which came a little after that. They remained in service until 1990 when they were sold off.

 KELVIN OLD MODEL MARINE DIESEL ENGINES

 KELVIN 4 CYL. OLD MODEL DIESEL ENGINE, SIMILAR TO THAT FITTED AT ONE TIME, IN THE MATAROA.

KAWAU FERRY MAIRE, WITH HER 4 CYL KELVIN DIESEL c 1950s 

MATAROA POST HER KELVIN DIESEL ERA 

Kelvin diesels are slow-revving, high-torque engines used mostly in commercial fishing and tugboats. The MATANUI is the only pleasure craft I am aware of that has, or has had, one of these beautiful engines, which run like a well-oiled sewing machine with an absolutely silent exhaust out the stern, well above the waterline. In the case of the MATANUI, even at cruising speed, all one heard was a very gentle hissing sound. The engine was painted a bottle green.

I went aboard her during the Joe Kissin era in 1946/47 and she had it then, having had it for a good number of years, notwithstanding that she had several engines in her long lifetime of over 100 years now. 

One unusual thing to note was that her Kelvin started on petrol and then switched to diesel after starting, which is unusual in pleasure craft.

KAWAU ISLAND TO SANDSPIT FERRY, MAIRE. 

The Sandspit to Mansion House Bay Kawau ferry – MAIRE, was built by Roy Lidgard in his boat building shed at Smelting House Bay, Kawau, in the late 1940s for Allan Horsfall, owner of the Mansion House Guest House/Hotel. She was fitted with a 4-cylinder Kelvin Marine Diesel engine and was part of the ferry services to the island right up until the property was sold to the Historic Places Trust around 1977. 

I am personally only aware of two specific installations, I know that quite a number of these engines were fitted to some of the fleet of classic trawlers built from around the 1930s to the 1960s by boatbuilders such as P. Vos, R. Lidgard, Shipbuilders, and others. Some examples , which may or may not have had KELVIN engines include boats such as Eddy Mansfield’s WAIWERA, the Owens brothers’ (Gordon and Jim) KAIWAKA, WAIMANA, FOX II, DALMACIA, and COBRA, among others. I believe the two main engine brands of choice by the owners of those lovely classics were Gardner and Kelvin. Any knowledge of vessels fitted with KELVIN engines, would be appreciated.

The company that produced the KELVIN diesel engines was founded in the UK in 1904 and has undergone a succession of ownership changes over the last 120 years. It is presently owned by British Polar Ltd. However, notwithstanding all the various ownership changes, the name KELVIN has been retained up to the present day.

DOOSAN 6 CYL 200 HP MARNE DIESEL ENGINES

NGARANUI WITH HER DOOSAN 200 HP 6 CYL MARINE DIESEL ENGINE, which replaced a Detroit 6-71 marine diesel engine

NGARANUI SHOWING HER AUXILLARY PROP  

NGARUNUI was built in 1955 by Jim Young and started life, with a 1942 GM Detroit Marine Diesel engine (ex-war assets). It has now been fitted with a late model 200hp DOOSAN Diesel and has a Yanmar 20hp diesel auxiliary engine, with the prop for that engine mounted immediately above the main propeller. 

MERCEDES BENZ MARINE DIESEL ENGINES & M.A.N.& M.T.U.  MARINSATION VERSIONS OF THESE ENGINES.

PACIFIC MERMAID WITH HER 2 X V10 600HP MAN MERCEDES BENZ MARINE DIESEL ENGINES.

Mercedes Benz, as the world knows, is a huge conglomerate with many divisions under various names and entities.

In the case of marine diesel engines, they are marinized under their own name and by various other marine engine companies, which have marinized them under their own company names. There is also a huge range of engine sizes and horsepower options. In New Zealand, we have had many installed in new craft built here for offshore owners. Most of these offshore exports, would have been under the M.A.N. or M.T.U. brands, as these brands of engines are typically of the larger horsepower ranges.

Regarding engines used in New Zealand, Im aware  of only five boats however, there are undoubtedly others. Nevertheless the total number of such engines remains quite small. So, if anyone knows of other craft in this group, please add them to the list.

The boats known to me include the PACIFIC MERMAID, a 105-foot super luxury motor yacht, fitted with two 10-cylinder 600HP., intercooled, artificially aspirated engines, with twin exhaust-driven turbines, marinised by M.A.N. She was built entirely in Auckland by Ken Winter and his family in South Auckland, with the build completed in 1989. He owned her until his recent passing, in Auckland. 

Ken W. usually ran her engines at a modest 1400 RPM, achieving a hull speed of about 10 knots.

PACIFICA MERMAID’s galley  distribution & control switchboard – starboard alternator in use. She has 2 x John Deer turbo 6 cyl. diesels driving 2 X 230/400volt alternators to supply her 230volt single phase 400volt 3 phase power supply, when away from her berth, which supply enough electricity for about 12 houses each

‘OHORERE AS AT 2025 WITH HER 2 X 770 HP MTU MARINISED MERCEDES BENZ DIESELS.

MTU MERECEDES BENZ DIESEL ENGINE – POSSIBLY SIMILAR TO THOSE IN THE OHORERE

OHORERE, was built by Percy Vos in Auckland, for the government of the day, to be a high-speed fisheries patrol craft, and designed by Thornycroft in the UK. However, she never reached anything close to her anticipated speed projections, as required in the order from the government, to the designers, and builders. Large sums of money were spent collectively, by the designers, Rolls Royce, who supplied her original engines, and the builders, to give her better performance, but they failed miserably, and she was ultimately sold to private ownership, where she has been used for many years now, I am told, for fishing charters in Tauranga. 

The 2 x 8 cyl. Rolls Royce’s were replaced about two years ago, with 2 x 770hp MTU marinized Mercedes Benz diesels, and is now capable of around 30 knots.

The engine in the image is used, which because of the huge cost of them new I feel it would be most likely & also most practical to install used engines.

The only other boat I know personally, is my own 1953 Roy Lidgard-built, 31-foot FLYING SCUD, which I bought in 1970, with her original twin Austin Skipper 100 marine petrol engines. 

I replaced them almost immediately with two OM321 100 HP Mercedes Benz 6-cylinder diesels. I sold her six years later, when I started building my 40-foot Vindex, TIARRI, and a later owner replaced FLYING SCUD’s Mercedes Benz engines with two Bedford diesels.

LADY KIWI (EROS), POST HER PERKNS 510 C.I. V8 MARINE DIESEL ENGINE ERA

VALRAY WITH HER 2 X S6 PERKINS 6CYL MARINE DIESEL ENGINES

Whilst there are many thousands of Perkins engines in use in NZ of various types, the two referred to above are rare. The S6 engine was developed for the military in the UK during WWII, and Ray Hamilton, the harbour master for the Sandspit area at Warkworth, managed to import two of them a few years after the war. He kept them in a big, beautiful shed on his Warkworth farm for a good number of years until he eventually built his dream boat, the VALRAY, in that shed in the 1960s.

The 510 cubic inch, 165 hp V8 Perkins diesel engines are in only four boats that I know of. The Eros (Lady Kiwi) had two fitted when new, the Moana Lua had one fitted around the 1990s, I believe. I had two of them put in my own boat, TIARRI, a modified 40-foot Vindex, (we added an extra 18 inches of beam) when she was being built for me, and launched in October 1979. There is also the P Vos built KAIKOURA, which had her original two 165 hp Kermath Seamate Special petrol engines replaced by the Bridgeford family of Mission Bay, owners at that time, in the 1960s-70s. She has had two Perkins 510 c.i. V8s ever since. 

FOOTNOTE: I have not written about or included very small, very old engines and boats from the very early days of the 1800s to the early 1900s, where engines seemed to me to be mostly New Zealand-made, of one-, two-, and three-cylinder types. I have read some excellent, very knowledgeable writings from Harold Kidd, on these, and as he is an expert in this very specialized field.

INPUT ex ALAN SEXTON – Another great read from Ken and as usual a few comments following Ken’s sequence

Another relatively rare installation in NZ was the Cummins VT-370M, 785 cu.in turbo diesel. These were fitted to John Wiles Salthouse Giovanni II (since replaced with a Volvo), the Pelin Shikaree “Neureus”, owned by Haines Hunter’s Denis Kendall and twins were installed in the Wellington Police boat Lady Elizabeth II (the one that sank). This model engine was superseded by the Cummins VT-903M, approx 450hp, with a pair installed in ~55′ Pelin Eclipse “Trident” in the 80’s

Kelvin diesels – I believe there was a bit of a “Holden vs Ford” mindset between commercial fishermen when comparing Kelvin and Gardner diesels, I remember an ex fisho I worked for many years ago being a strong Kelvin man and very “dismissive” of Gardners

Doosans, Lees were selling these for a while. Another notable installation (a 320hp) was Conrad Robertson’s sedan launch Rampage , originally built for himself. I understand she has since been re-engined (Cummins?) and cockpit has been extended

The MAN V10’s from the 80’s mentioned were derived from a JV between Merecedes and MAN, https://www.curbsideclassic.com/blog/truck-history-the-man-18-3-liter-v10-the-last-on-highway-turbodiesel-behemoth-in-europe/ so are considered genuine MAN’s. Other notable installations include the Ted Ewbank designed “Kiwi Challenge” support boat for the 87 cup challenge and Neville Crighton’s Alan Warwick design Countach, both I believe 750’s. By the way Pacific Mermaid is advertised as being built by Salthouses.

The Perkins S6 was developed in the 1930’s for heavy trucks and was an enlarged version of the P series. https://archive.commercialmotor.com/article/21st-october-1939/26/perkins-ii-ices-new I believe the first installation in NZ was in Alan H’s “favorite” launch, the original Vindex. Wasn’t there for very long, replaced by the lighter and more powerful T6.354 in the mid 60’s

There was another launch written up in Sea Spray in the late 60’s which had a 160hp Perkins 504, cannot remember her name

Moana Lua has had quite a few engines in her life, I believe the current engine is a John Deere. When she was owned by Ken Burrowes from the late 60’s to early 80’s I understand she was originally equipped with twin petrol engines and then Ken replaced them with a “Torpedo” brand diesel engine (I thought he was pulling my leg when he first told me this), which i assume was from this factory https://tractors.fandom.com/wiki/Torpedo_(Rijeka)

Another quite common installation was the petrol Chrysler Crown, a marinised flat head Dodge. Eastern Star, Shipbuilders 32 previously featured here was built with one. This was replaced with a 75hp Ford in the early 80’s.

09-05-2025 INPUT ex JIM LOTT on Kelvin engines – Around 1981 I removed a Kelvin diesel from a yacht and replaced it with a Yanmar 2 cyl. The Kelvin had a crank start fitted and I don’t think there was an electric start at all. I am pretty sure it was 2 cyl. It was fitted in the 34ft Ladybird design (Bert Woolacott) named “Aorangi”. 

Aorangi was built by Ron Evans who lived at Bucklands Beach and Ron was a commodore at BBYC and later on manager at John Burns and Sailors corner. He built Aorangi late sixties or early 70s using full length kauri planks. The owner of Aorangi who I worked for was AAH Schulte, known as Hubert. The bottle green Kelvin was tucked under the cockpit driving through the quarter.

I was more interested in the new Yanmar I had to fit so I did not take too much notice of the Kelvin but I recall Hubert telling me he had given it to a transport museum. The Yanmar worked out fine and I moved the shaft to the centreline.

INPUT 04-08-2025 Perkins T12: A Wartime V‑12 Diesel Prototype

Purpose & Origin – Designed just before WWII, the Perkins T12 was intended for naval craft (motor launches, gunboats, torpedo boats) to replace petrol engines and free up Rolls‑Royce Merlins for aircraft use  .

Design & Specs A 55° V‑12 (two inline‑6 banks on a single crankshaft) with 6″ bore and stroke, giving roughly 33.3 L capacity. Each bank had independent systems (water, oil, fuel injection), enabling one half to run if the other failed  . Featured an unusual centrifugal supercharger driven from the crankshaft. Only 5–6 prototypes were built, with two installed in a Royal Navy launch (ML 570) from late 1942 through WWII  .

Performance & Fate It achieved the target ~1,000 bhp, but production never followed due to the availability of cheap American petrol engines  . After the war, one engine served as a stand‑by generator at the Peterborough factory into the 1980s  .

🔗 Links with Rolls‑Royce

Direct Association: The design was meant to replace Rolls‑Royce Merlin petrol engines in marine craft—similar size and layout for direct substitution  .

Personnel Connection: Perkins was founded by Frank Perkins and Charles Chapman—the latter previously worked closely with Rolls‑Royce founding engineer Henry Royce  . Chapman’s expertise evidently carried influence from aero‑engine principles into the T12 design.

Summary The Perkins T12 was an ambitious, Rolls‑Royce‑inspired diesel V‑12 project to militarize petrol-dominant craft space. Built quickly (~14 months) under Charles Chapman’s leadership, it showcased clever redundancy and performance—but never reached mass production, sidelined by US petrol engines. There does not appear to be any direct Rolls‑Royce technical design partnership—rather, the association comes from the T12’s role as a diesel counterpart to the Rolls‑Royce Merlin, not from a joint development.

NZ’S UNIQUE MARINE ENGINES – Part One

Todays WW story is a little (or maybe a lot) out of the normal WW story style i.e. we are focussing on marine propulsion > engines not craft.

The story has been pulled together by Ken Ricketts, who comments while he has endeavoured to be as factual as possible there will always by matters others will either know more about or be able to correct errors – so woodys do not hold back in commenting.

There are many sections to the story and the intention is to publish one part a week. 

WW are very conscious that most readers have limited interest in engines, h.p., gearbox ratios, prop sizes etc – BUT a very high % of the WW site visitation is research based, so the thinking is this data needs to be recorded for future recall. HOWEVER if the viewing numbers show low interest, an option is to just load the data up in one go.

So woodys over to you have a review / look and lets see the interest factor.

As per any Ken Ricketts item it will be riddled with typos and mistakes, but as stated the primary intention is to get the data in a location for future access. Over time we will ‘fine tune’ it.

NOW BELOW, W1 AS A FULLY AIR CONDITIONED LUXURY PLEASURE CRAFT, AS AT 2025

W1 – WITH HER BEATUTIFUL GENTLE FLAT WAKE AT 22 KNOTs c2020 

W1 – HER ENGINE STORY. 

All RNZAF craft, have a permanent identification number, allocated  to them upon entering RNZAF service, & whilst only the number is ever actually sign-written on the boat, in all paperwork, & in the spoken & written word, they are all prefixed with a letter, & in the case of this craft it is a “W,” thus the craft referred to herein, was IDed as “W1” when it arrived in NZ & was therefore known  as “W1”, which has now  been given this title, as the boats official name, along with the special marine RT call sign of ZMWI.

She was originally imported new from UK by the RNZAF c.1940, & after her RNZAF service ended in c.1951, her designation & name of W1, was changed to CARROMA in the 1950s, by the Alright family, of Panmure, who did the first & second pleasure craft conversions to her, to become a pleasure craft, & now it has been reverted back to W1 by Francis Uren, the present owner who has created a 3rd new super luxury set of coamings & fully airconditioned fitout. 

She had 3 of these 500hp W12 cyl engines which were in 3 banks of 4 cylinders, as per the above image, as original , with the 2 outer engines facing aft, with conventional mechanical gearboxes, & the centre engine facing forward, driving a vee drive/reduction gear unit, so all 3 propellers, where in a  perfect line across, at the stern, (refer above image), as original, when ordered by the RNZAF in early WWII.

During her WWII service, she had to have a fulltime engineer, sitting in a padded chair, with soundproof earmuffs, in the engineroom, when the engines were running, & when she was at sea, controlling the gearbox reverse leavers on instructions from the bridge, & supervising the engines. 

The original engines were replaced initially, in the early 1950s by twin 6/71 GM Detroit diesels, by the Alrights, & later by one 600HP 8V/92-TI Detroit by current owner Francis Uren. post 2010 which she still has today.

HUDSON HOME MARINISED 6 CYL PETROL CAR ENGINE.

HUDSON 6 CYL PETROL CAR ENGINE as used in the yacht SUNDOWNER. (image unavailable)

Only one yacht/motor sailer called SUNDOWNER had this 1930s vintage engine, which in the later 1940s, had an issue with one cylinder & piston, so in the typical NZ No. 8 wire fashion, the owner of the day, simply removed the offending piston, & made it into a 5 Cyl Hudson home marinised marine engine. —It ran well enough, it but sounded funny in the exhaust.  

STUDEBAKER 1930s HOME MARINISED FLAT HEAD 6CYL TRUCK ENGINE

This was a very quiet, smooth running, reliable, low revving engine, originally fitted to the ROYAL FALCON, in the 1930s, & was replaced in the later 1940s, with a factory built marine petrol engine, & the Studebaker was sold to  Bill Waters, who installed it as original, in the 34ft GAY DAWN, in the early 1950s,  as she was being built by him & his son Brian. 

Ralph Ricketts, bought GAY DAWN in 1956, with that engine, & replaced it in 1958, with twin diesels, – (refer later engine listing.) RR sold it.

CROSSLEY MARINE DIESEL ENGINES 

A TYPICAL SMALLISH CROSSLEY ENGINE, PERHAPS SIMILAR TO THAT IN THE LADY CROSSLEY

LADY CROSSLEY POST 2020 

There is the only example known to me, of these engines, in NZ pleasure craft, & that was in her namesake boat, the beautiful LADY CROSSLEY, built for Seager Bros. Ltd Auckland, who were the agents at that time, as a demo boat for these engines. 

However, they were 2 cycle direct reversing, — (as are all or most direct reversing engines), — which meant that one had to stop the engine, & restart it, running the opposite direction to go in reverse, which of course had to be done in the engine room, on directions from the helmsman, up in the bridgedeck. this was highly unsatisfactory, & quite dangerous in this type of use, & after only a very short time, they were replaced by twin Gardner 6LW diesels which she had for many years & may still have.

FAIRBANKS MORSE MARINE DIESEL ENGINES

AUCKLAND HARBOUR PASSENGER FERRY, WITH FAIRBANKS MORSE DIESEL ENGINE c1950s

THE LADY MARGARET ENGINE STORY 

Whilst these are mostly used in very large versions in ocean going ships, & large craft, they did or do make smaller engines & there was at least  one example of these in Auckland, I am aware of, & there may be others,  & that is in the 1939 Dick Lang built, LADY MARGARET, for Ted Clark, who installed 2 of them, when she was built, which were ultimately replaced by 2 x  6 cyl Fodens, in the mid/later 1950s. (no image available of  Fairbanks engine)

AUCKLAND HARBOUR PASSENGER & VEHICULAR FERRIES 

These engines were also used for many years, in Auckland Harbour vehicular & passenger ferries, in a very slow revving, 4 cylinder direct reversing, —  (must be stopped & restarted, to run the other way for reverse), — 2 cycle version, with 2 engines, with one engine facing a propeller at each  end of the boat, up until the Harbour Bridge opened in 1958, except for one or 2 passenger ferries, that had one single 8 cyl version, & I think a few passenger versions may have been  kept in use, for a year or 2 after 1958.

NORDBERG PETROL MARINE ENGINES 

NORDBERG 100+hp petrol engine, similar to those fitted as replacements for original engines, to LADY DIANA & MAKURA

LADY DIANA. AS SHE LOOKED. WITH HER NORDBERG PETROL ENGINE. – EX B WORTHINGTON.

MAKURA IN HER EALRY DAYS – THE NORDBERG ERA

NZ agents for these, were Seabrook Fowlds Ltd Auckland, in the 1950s, & the M.D. Phil Seabrook, had one fitted to his LADY DIANA, replacing her original Austin Skipper 100, in the later 1950s, for which his company also held the agency, at that time. 

A second engine was fitted to his brother-in-law, Cranston Leighton’s MAKURA, after he sold her to brother in law Phil Seabrook, in the later 1950s. 

Both of these engines have long since been replaced with diesels, & they are the only 2 examples that I am aware of, ever in pleasure craft, but of course, there may be well others, & look forward to any input from other boaties or engineers to confirm this, but these engines never became really popular & a big seller.   

RUSSELL NEWBERRY DIESEL ENGINES.

MOVARIE WTH HER 2 RUSSELL NEWBERY 40HP MARINE DIESEL ENGINES. c. LATER 1940s. 

These are made by the RN Diesel Engine Company Ltd., which was founded in UK in 1909, & is still manufacturing engines today in UK, & there is only one example in NZ, that is the 1938 built MOVARIE. 

These were 2 x slow revving 4 cyl., 4 cycle engines & were 40 H.P. Russell Newberys, as original, which were eventually replaced by 2 x Ford Diesels in 1960.

BMW MARINE DIESEL ENGINES & STERN LEGS.

BMW 6CYL MARINE DIESEL ENGINES WITH STERN DRIVES 

While made in fairly substantial numbers by BMW, only 1 pleasure craft in NZ  had them, which was a standard designed Formula 4000 Vindex & it had 3 of them with stern drives. 

LEYLAND MARINE & MARINISED DIESEL ENGINES.

SHENANDOAH WITH HER LEYLAND TRAIN ENGINE

There are a very few Leyland engines that were ever fitted to pleasure craft, & are all 6 cyl., except for the LANAI. which has or had, 2 x 4 cyl. Leylands. 

Other craft included the RAIONA, with a Leyland Comet, fitted by the Alf Secombe, in place of a previous petrol engine. Also, there was the Guthrie’s Leyland Comet, the original engine, in the ISLE OF ARRAN. 

The SHENANDOAH also had a Leyland 6cyl. home marinised train engine which was fitted around the 1990s. 

Ralph Ricketts fitted 2 x Leyland Cub Diesels to the GAY DAWN in 1958-59 in place of its previous single Studebaker truck engine, later removed & replaced by a single Ford Diesel, by a later owner.

The only other pleasure craft was a Leyland Cub installed in the 30 foot SAGA, by owner/builder, Kings College master, Mr Val Maxwell. 

The beautiful big bridgedecker BLITZEN, is/was also powered by 2 x Leyland Beaver, locally marinised diesels.  

Ralph Ricketts fitted 1 Leyland Cub to the JULIANA in 1947, which he removed in 1956 & replaced with a 4 cyl Buda Diesel, he bought from John Warren who had removed it from his ARCTURUS, that had been built for him by McGeady a few years earlier, & he replaced the Buda with a 6 cyl diesel. This was replaced in the JULIANA, with a 6 cyl Ford Diesel, by the owners of the day, the Algie Brothers, of Algies Bay, Mahurangi, about 20 years later.

RR fitted the Buda to the JULIANA in place of the Leyland because he had another brand-new complete engine, & he fitted the 2 of them in the GAY DAWN in 1958-59

Two Leylands were fitted to the iconic passenger ferry BAROONA, replacing her previous single engine, around the later 1950s/60s.    

THORNYCROFT MARINE PETROL ENGINES.

Thornycroft engines had always been produced in substantial numbers in UK, however only a tiny number, in pleasure craft in NZ.

The tram topper MANOWAI had one, in the Claude Atherton era of the 1930s & up to the later 40s, which had 1x overhead valve & 1side valve, as many Thornycrofts, did for many years. He replaced that engine with a twin cyl. Ruston Diesel for use, after that time, as a longline fishing boat. The second & third Thornycroft’s were in the RAUTANGI, & both fitted by or for, Les Sterriker, of Sterriker Engineering, in Kyber Pass Newmarket, one after the other, the last being larger with more HP., than the first one, it was eventually replaced by a Ford Diesel by a later owner. 

There is or was also, around the 1970s/80s era, a UK custom purpose-built rescue craft here, painted orange & blue, fitted with 2 x Thornycrofts, which was moored at Matiatia at one time. 

RQLPH RECKITTS  purchased the JULIANA in 1946, & she had a 1920s vintage Thornycroft Tee head 4 cyl petrol truck engine home marinised, running on salt water, which was her original engine, when she was built by Sam Ford, In 1930, which was absolutely identical, to that shown in the image attached, which was not in very good health, when RR bought her, so he  immediately totally rebuilt it in 1946 himself, not knowing at that time, he would be removing it in 1947, to fit a Leyland Cub diesel in its place, he had later acquired, & he fitted an additional distributor ignition system, as part of the rebuild, of the Thornycroft, as well as retaining the existing magneto, giving her dual ignition.

MEADOWS 2 x 6 CYL PETROL ENGINES fitted to TEAL flyingboat harbour patrol craft c1950s

Only 1 of these engines used in pleasure craft, it was a 4cyl version painted bottle green, as they all seemed to be, (as were all the Thornycrofts as well), in the 30ft bridgedecker LEAH, for Dick Daniels in the mid1940s. 

TEAL had 2 of them in some harbour patrol craft for flying boat patrols fitted with twin 6 cyl versions of the engines) the RNZAF.also used them in a number of their patrol craft, in the 1940s to around 1960. 

AEC DIESEL ENGINES

INEAWA WITH HER AEC  6 CYL home marinised, DIESEL ENGINE

Only a handful of these beautiful smooth quiet running UK built diesel engines, in pleasure craft in NZ, which are now no longer made. The AEC company was bought by Leyland many years ago, & production eventually ceased. They can be compared very favourably to an 8L3 Gardner, with their sound, & smooth quiet running. 

There is at least one large bridgedecker similar to the BLITZEN that has 2 of them & also at least 1 other single engine, smaller boat.

FAY & BOWEN PETROL ENGINES

MAGARET S with her FAY & BOWEN 6 CYL MARINE ENGINE

There has only ever been one boat with one of these engines, & that is the MARGARET “S,” which had one from 1923, until after 1967, now almost certainly replaced by a diesel, as most boats are, these days.

LOEW VICTOR (KNIGHT’S PATENTS), 4 CYCLE PETROL ENGINES

A 32ft launch was built by Bailey in 1913, with a 25H.P. engine of the same name, showing a good turn of speed in the images, however she appears to be one of just a small number of craft with these engines.

BUDA PETROL & DIESEL MARINE ENGINES.

PETROL ENGINE, WHICH HAD DUAL IGNITION, WITH 12 SPARK PLUGS, FED FROM A SINGLE 12 POSITION DITSRIBUTOR CAP, & A BENDIX REVERSE CONTROL SYSTEM, & THROTTLE, WTH 2 LITTLE 6 INCH LEVERS, IN A DUAL SMALL CONTROL UNIT. – VERY RARE IN THOSE DAYS.THIS WAS HER ORIGINAL ENGINE FROM NEW, WHICH SHE HAD FOR A GREAT MANY YEARS, & OWNER, BILL RYAN, IS STANDING IN THE DOORWA.

MAHARATIA IN EARLY YEARS, WITH HER TWIN BUDA 6 CYL DIESELS.

Only a comparatively small number of these in NZ, because the company was bought by Allis Chalmers in 1953, & manufacturing finished that year.

There were however 5 in total, fitted with 2 to the AMAKURA, during WWII, by the navy, which were removed & replaced by 2 x Graymarine petrol engines, by the owner of the day, a Mr Widderspoon in1947-48, as they were belching huge amounts of black smoke out both sides, as she had side exhausts by then. She was moored at that time, at Hobson Bay, just by the Judges Bay bridge, under the other side. There was also the ARCTURUS, that had a 4cyl Buda Diesel installed during construction.  

The MAHARATIA also had 2 x 6 cyl Buda diesels as original, when built by Roy Lidgard, & at his Kawau Island property in 1947 & towed to his Auckland shed to have her engines fitted Auckland shed, which were a number of years later replaced by 2 x 6LW Gardner Diesels.

The 32 ft ARCTURUS was fitted with a 4 cyl Buda Diesel new, by boatbuilder Mac McGeady, (Supreme Craft Ltd) for John Warren, of Mission Bay, with installation by Tracy Nelson, which John W., later sold to Ralph Ricketts, & which was then installed in the JULIANA, for many years. Ultimately removed by the Algie Brothers of Algies Bay, Mahurangi, & replaced with a 6cyl Ford Diesel around the 1990s.   

DAIMLER BENZ V12 DIESEL ENGINES

HYDROFOIL MANU – WAI, WITH HER V12 DAIMLER BENZ 1350HP DIESEL ENGINE

Only ever been one craft in NZ that had one of these engines. They ran at comparatively low revs (under 1500 RPM) & had to have hot engine oil pumped through the engine for 20 minutes before starting when cold.

This craft was the Auckland based passenger ferry MANU-WAI, which provided the first high speed passenger services to Matiatia Bay at Waiheke Island, & also to Pakatoa Island, in the Hauraki Gulf. The engine was based on a marinised aircraft engine of around 1400HP., with engine revs governed to around 900rpm

VM DIESEL MARINE ENGINES

TWIN VM DIESEL ENGINES 

LADY KIWI (EROS) WITH HER TWIN VM DIESEL ENGINES

These engines are still made by VM Motori Ltd in Italy which started life as a standalone company, in 1947, however it has had a checkered career, of various part owners, & has ended up today fully owned by Stellantis or Fiat. 

The only boat with these engines, is the first 40 ft Vindex to be built, designed by Jim Young, & built by Orams, of 2 skins of Kauri, in Whangarei, in 1972.

She is the EROS, built for Auckland bed manufacturer Alf Broadhead, sold when he died, & is now renamed LADY KIWI, & her original engines were replaced probably around 15 years ago now, by the above 330 HP versions of the VMs.

STEARNS MARINE PETROL ENGINES WITH ONE SIMILAR TO ONE OF THOSE ABOVE, FITTEDTO THE COLIN WILD BUILT LADY MARGARET, AS ORIGINAL  

STEARNS PETROL MARINE ENGINES c1926 

LADY MARGAARET (BUILT BY C. WILD) WITH HER STEARNS 165 HP PETROL MARINE ENGNE c1929 

F B Stearns was born into a wealthy family, & by his teen years, had developed a passion for cars & engines, so his father “indulged” him, with the creation of F B Stearns & Company, being established, in the late 1800s, & by 1907 the it was producing its first production run of vehicles, with a side valve engine he had built.

In 1911 he developed an association with the Willys (Overland) organisation, which had already developed a beautifully quiet smooth running “Sleave valve,” engine & his company from then on produced all sleave valve engines & their cars were from then on, known as “Stearns Knight.” 

They also manufactured marine engines. Steans retired from the company actively in 1919, & it was sold to Willys (Willys Overland), in 1925, & the company was wound up in 1929, so Stearns marine engines were only ever produced for a very few years.

Auckland businessman H. O. Wiles acquired the NZ agency for Stearns marine engines, sometime around the 1920s & fitted a 165HP Stearns engine to the beautiful 42 ft LADY MARGARET, that Coiln Wild built for him in 1927.

She was very fast for her day & he entered her in various competitive events successfully. 

She is one of our all time great classics of NZ, & these days, sports an artificially aspirated 6 Cyl Ford diesel.

EROS

photo & details ex Harold Kidd

The above photo is of the 34ft launch EROS racing in the 1929 Anniversary Regatta in the race for cruisers over 12 knots.
Stan Parker of Parker Engineering bought her in late 1927/early 1928. She was supposedly “well-known on the Manukau” prior to that, but who built her, under what name and when HDK hasn’t yet figured out.
Maybe she was built by Les Coulthard?
Stan Parker re-engined her with a 100hp Hall-Scott (probably an aero-engine) and set about racing her with the NZPBA, Victoria Cruising Club and Devonport Yacht Club. She was an 18 knotter.
Stan sold her to W. Fullerton in June 1935 and took Fullerton’s NOMAD in exchange which he then handed over to Lidgards to completely rebuild, extending her from 35ft to 42ft and renaming her ARAWA. NOMAD had been built in 1919 as IRIHAPETI but is now a bridgedecker known as REHUTAI but supposedly with “Lanes” as her builder and a build date of “1949”.
Fullerton sold EROS off immediately to J. Gresham of Tauranga who had her until at least February 1938.
So, what were EROS’ origins before Stan Parker and what happened to her after 1938 in Tauranga?
