Re: [Electric Boats] Cruising with EP

Thanks Kevin,
I have pretty much decided that my little 3.1HP motor and tranny/axle set up will not be enough to push a 40' x 14' houseboat very far, fast, or for very long. I have decided to use it to make an e-vehicle that maybe we can take with us on our trip to use whenever we dock somewhere. Do you think a 60hp electric motor would be too much for a houseboat this size?

Hello William,

Positive track has a friction clutch built into the diff. This is not a solid axle and has spider gears but the ability to freely move is limited by the friction clutch. With a true diff. spinning one axle will make the axle on the other side spin the opposite direction. This same action will take place with posi-trac but will give resistance to this action.

Hello Robie,
What do you mean by positive track differential? Does it mean that one axle can turn, or not turn, independently from the other? How would I know if my axle has it? Thanks for your help.

One word of wisdom or food for thought. Befor you get too far down the rabbit hole, make sure that the Golf Cart Rearend/axle is a positive track differntal. Other wise the alt will lock up the free spinning side while the prop turns. We tried this a few years back on a differnt project only to find out we needed a differnt 3rd member.
Cheers
Robbie
