[Electric Boats] Electric motor for 33' Sailboat

 

Hello,

Has anyone done a comparison of existing electric motor / controller packages in the 6-8hp equiv range? I am not very interested in re-inventing the wheel. I can find 4 packages available from;

Beckman electric – uses gearbox - 24 volt system $4,290.00 48 volt system $4,910.00 The motor / gearbox seems well thought out, but the web site and details are weak.

Electric Yacht - $3,995 motor only – 130lb system, $5495 – 260lb Excellent web site, motor seems to use belts, which is odd (can only find a pic in one of the video's)

Technipower / Solomon – ST 37 - $9,390 motor, $14,203 complete, very well proven system but seems too expensive unless efficiency is much better.

Thoosa 6000 6kW Drive System, 48V $7,007.00 motor, $9,000 complete. Looks new to the market,

If anyone has done an analysis, looking at efficiency, etc, or has any imput / suggestions I would be very interested.
