Re: [Electric Boats] Re: Retrofiting a classic

 

Matt can you enlighten us a little more on your setup. What motor? what volts? and what speed? pictures work also.

Except the Nuke plant doesn't need to breath like the diesel, so they
can stay down deep and not have to come up to breath.

I don't think most of our boats are large enough. My boat didn't even
have a gear box, the two-stoke petrol engine was connected directly to
the prop. It's going to be a bit hard to increase the transmission
efficiency of a steel rod!.
(And it still doesn't have a gear box or reduction gear, it runs quite
happily now with a permanent magnet motor bolted straight to the prop
shaft).
