I have begun the steps to convert my small fishing boat from an ancient v8 (1978)gas engine to a sweet electric motor. The vessel is a 78' searay 20' long. With its gasoline engine and full fuel tank it weighs around 3,500 lbs. Don't know what it will weigh after the enginectomy and transplant but I'm certain that I'll find that out. So apart from all the usual hundreds of questions that confronts a diy person here is the biggie- Drivetrain- can the existing stern drive be used to provide propulsion? I get that I don't need the transmission gears since i'll have the electric controller but the sterndrive is also the rudder and the screw so...(don't you just love newbie questions?) I of course don't know what kind of power loss to expect from doing it this way but the motor is a 15 Kw motor and I certainly won't be pulling any wake boarders in the north pacific ocean (the lost coast 175 mIles north of San Francisco). I've got way too much experien ce with engines of every shape and description-sailboats (deisels), cars,jeeps,power boats from rebuilding, installing, to fabricating new motor mounts,etc. But here's the thing- in the 50+ years of enjoying mechanical things, when I'm to the part of holding the wiring harness in my hands and deciding the order, placement, and connections of that tangle of spaghetti in it's rainbow colors- well let's just say that's it's time for a long coffee break to read that part of the manual again.I'm confident that i'll get thru that park ok but has anyone been in this particular position before? Anyway the boat itself looks to be nearly perfect for my electric swap. The 42 gallon fuel tank in the bilge will come out and will become the batteries new home. The v8 will come out (yea!) and i'll have enough space for my motor plus new deck space to stand while fishing. Weight and weight distribution are much improved by the new motor and batteries. My thought right now is to fabricate a co upler ( heim joints or ujoints as well) hook the motor to the input shaft of the stern drive and bobs your uncle-off I go. Yes I know that it's going to be a couple months of toil, trouble, mistakes and some money spent but still off I go. So that's the big question for someone who has been down this path before -can I connect an electric motor to a stern drive in a power boat and have it work? BTW the term "power boat" takes on a whole new meaning when it's electric don't you think? Thanks so much for reading this. greg
