More news from the Boat Show: today I had a longish talk with Ricky Cole of epropulsion who apparently used to work for Torqeedo. With regard to shaft length you could shorten the epropulsion "Spirit" motor in the same way that I suggested for the Torqeedo (see Library) if Graham's superior method (which avoids altering the motor) can't be implemented for some reason. However he said that epropulsion are thinking of introducing an "ultra-short" shaft version. There definitely is an extension cable allowing you to operate with the battery detached from the motor. Indeed, early next year they hope to introduce a remote version of the motor, i.e. with remote throttle adjustment as well as a separate battery.
Don't even think about using their bigger "Navy" motor. You can't afford it either in cost or in the weight of the batteries needed in the boat!
Graham, yes Baseline are not the cheapest! (but convenient for me since more or less "local"). At least we know the things called an "hatch hinge". Whether my Torqeedo would have benefited from a visit to Seamark Nunn I don't know; I do know that it's performance is not what it once was, presumably since the batteries are ageing - I've had the motor for five or six years now. It's still adequate for my canoe or 15' dinghy, but not for Seatern. I had the propeller off recently to check and packing the back of the propeller with grease seems to have protected the thrust washers from rust damage. The same washers on the epropulsion are 316 stainless, by the way.
