I replaced my Atomic-4 (rated at 30 hp, but probably, really closer to 20) with a 10kw kit from Thunderstruck. It worked well in my Pearson 30 (30 feet, about 8300 lbs. displacement) sailboat. I was limited by the small battery bank, but it got me in and out of the cove where my mooring is located. I used the same prop that I was using for the A-4.
I since upgraded boats to a Pearson 365 (36.5 feet, ~18000 lb displacement) with a Perkins 4-108 in it. The diesel runs well, but is 43 years old, and I am thinking I will, at some point, replace it with a 14kw, 72v, liquid cooled electric at some point. I figure I should be able to mount the motor where the v-drive is currently, and the batteries where the engine is. But we'll see.

Just wondering if anyone can give real life experience with replacing a 20hp or 30hp diesel with a 10kW 48V electric motor diy. I am aware of the conversion and inefficiency allowances etc, but in actuality, is it more like a 20hp or 30hp, assuming same prop and configured rpms etc?
