Pembroke Engineering Works
Hampton Wick, Kingston upon Thames

I had always assumed the Watermota was a Waterman sold in Great Britain, but Peter Hunn's book leads me to think it was a rip off instead, or as Hunn diplomatically phrases it, "a clone of the 1916 forward-pointing cylinder Waterman". There is interesting (and sort of sad) information on Walter D. Fair & Co. in Hunn's book.

Remember, Waterman first produced an outboard motor in 1906.

The following info, copied from the web ( leaves me thinking there was a license agreement for outboards.

"Watermota, 1911 est.

WaterMota was established at the Pembroke Engineering Works at Hampton Wick, Kingston upon Thames in 1911 by Walter Fair as a subsidiary of Rigbys, a London gunsmith where he was the manager.

The first engines produced by the company were American Waterman two stroke inboard and outboard engines built under licence, similar in appearance to the copper jacketed K1 and K2 engines which were eventually developed by Fair.

However, one of the many innovative products produced by WaterMota in the initial years was a variable pitch propeller which could be set to allow speed, ahead, astern and neutral by altering the propeller’s pitch. This was a much improved version of the original variable pitch propeller thought to have been patented in 1895 and was in production until the late 1990s. The outbreak of the First World War severely curtailed the production of marine engines with production facilities given over to making Hyland Cocking levers for machine guns and a range of aircraft fittings."
