AN INSIGHT INTO NZ’S UNIQUE MARINE ENGINES – Part Five
Todays WW story follows on from earlier stories – link below to Part One, Two, Three and Four 
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 in commenting.

LINDA, AT CHRISTMAS 1948, TAKEN IN SCHOOLHOUSE BAY, KAWAU ISLAND, JUST AFTER HER LOEW-KNIGHT PETROL ENGINE HAD BEEN REPLACED, WITH HER GM DETROIT 165HP MARINE DIESEL.

COQUETTE, POST HER LOEW KNIGHT-ERA

I know of only two boats that have these very rare versions of the Knight sleeve valve engine. One is the 1928 Colin Wild-built LINDA, which was bought by Roy Swales just after WWII with her original Loew-Knight 6-cylinder petrol engine. I saw it running, and it was incredibly smooth, quiet, and looked very tiny in LINDA’s huge engine room. It was painted silver and had the name “Loew-Knight” in a scroll, cast into the inspection plates on the crankcase. 

Roy W. replaced it in 1947 with a 6/71 GM Detroit 165 HP diesel engine. 

The other boat was the delightful Logan-designed and built COQUETTE, with her sedan top, which was added many years later by Arnold Couldry. He kept her delightful lines perfectly with this addition. She had a 4-cylinder version of the Loew-Knight sleeve valve engine, also painted silver.  I tend to think this may have been her second engine because of her age, having been built in the early 1990s.

WHITE CLOUD LAUNCHING DAY WITH HER 4 CYL., HOME MARINISED FODEN DIESEL

There are only three pleasure launches that I know of that have these engines, and there are two with 6-cylinder versions. The LADY MARGARET (built by DICK LANG) replaced her original two Fairbanks Morse Diesels; the MARNINE, which had two of them from when she was built, had the same specifications and was installed at the same time as the LADY MARGARET. The third boat was the WHITE CLOUD, which had a 4-cylinder home-marinized version, fitted by or for, the managing director of Fodenway Motors, Penrose. They were the New Zealand agents for Foden engines at that time and had her built and baselined a generator set to convert the 4-cylinder Foden for marine use in his new boat. This installation took place at their Gt. South Rd premises after being built at 1A Summer St, Ponsonby, by McGeady (Supreme Craft).

In addition to these boats, all RNZN-owned HDMLs and the first of the Police Launches named DEODAR, (DEODAR I), had two of them installed. All were originally 6-cylinder versions; however, but with the HDMLs., some engines were later replaced with 12-cylinder versions in some boats, which were, in effect, two 6-cylinder engines side by side in one crankcase. These had one drive shaft and two crankshafts connected by a system of gearing. At least one twin x 6-cylinder installation is believed to still be in a boat & still surviving today. It is in the massively refurbished, now privately owned KUPARU, primarily located in Whangarei.

Foden engine manufacturing and parts supply were sold to Rolls Royce in the late 1970s, and production ceased when they took over the Foden manufacturing rights.
