Re: Prop Selection for Electric Motor

I'm mostly just building a pilothouse/dodger back to the wheel and using Elfeland frameless solar panels, which only weigh about 2 kg per 100 Watt panel. The 80 Watt panels allow me to put a porthole...

Re: Prop Selection for Electric Motor

The motor would be in the bilge then, and the motors are all 10,000 RPM max. The boat had a hydraulic drive, and the lower pump sat in the bilge water. Pretty sure I would lose more efficiency than...
