Re: [Electric Boats] Re: Hello, New to group - do I have enough data to consider conversion?

With a house boat he should have a lot of flat roof space. He could
get maybe 6000 watts of solar cell up there this would give him a good
7 hp in full sun. I am sure he already has a generator 7000 watts or
so for another 7-8 hp of continuous use even before we start talking
batteries. 14 hp continuous on a boat with a shallow draft such as
his should poke along pretty good at maybe 10 mph. Add some
batteries for short burst of speed here and there and I think it is
very doable. Just depends how he want to use the boat. In a house
boat I dough he is going faster then 6-7 knotts most of the time
anyways. Plus the solar cells and batteries will make staying off the
hook more enjoyable.

Here are some all electric motors: http://www.bellmann.nu/?nr=13
