How can i compare gas and electric motor power with eachother?
First do this thought experiment: Take out the old motor (500#?), add 1200 lbs batteries. Now clamp a 10 Hp outboard on. Put on really good ear plugs. At WOT you would get maybe 6-7 mph for 60 - 90 minutes. Maybe 4x run time at 4-5 mph. That's what your electric boat will be like. If that seems good to you go ahead. You are looking at several thousand dollars for a motor and controller that big. You would need a hefty charger too.Old deep V fiberglass hulls are a dime a dozen but are the worst possible hull form for efficient electric power. A boat shaped like a big canoe (think old sail boat sans keel) is the best design for easy propulsion.Denny----- Original Message -----From: stefSent: Saturday, October 09, 2010 6:22 AMSubject: [Electric Boats] Want to convert a glasstron 184 to electric. Any advice?Hello,
I've been leeching the group for a few months now, and became enthousiast in electric boating.
Currently have a inflatable with an little outboard electric, and i really love the silence, and the ease of boating. (never expected that..)
Now, i can get 32 batteries AGM 12V 80Ah for free from a relative (4 years old, come from a no-break system), so i want to convert a boat to electric.
Currently, i found a Glasstron 184 with a broken engine, but in exellent shape, and overhauled tailpiece.
Can anyone give me advice about motorising this speedboat?
I was leaning towards a 10 to 20Hp series wound dc at 96 volts, with 3 battery banks in parallel, giving me 96V and 240Ah.
Any ideas, or recommendations, before i actually purchase the boat?
Biggest question is if the hull of the boat is capable of being thrusted by electric, instead of the original 165Hp six cilinder inline...
Many thanks!
