Re: Engine overheating when motorsailing upwind

Check engine spec for maximum tilt. If you are heeled over, at some point the pick up tube will not be in oil. As you tilt the engine the oil flows down one side more than the other.

Re: Block windlass chain hole

On my Lofrans windless the chain drops straight down into the chain locker. I hooked up a stopper to the end of the chain when underway. No water gets in.

Re: Purchasing Boat in Panama, transport to FL

Is it a Panama flagged vessel? If not US documented, you will have to take care of that.

Re: Gemini 105mc conversion Diesel to EV?

Remember that 20kW at 48v is over 400amps!
You will never get 20kW if your system and internal battery resistance is more than a few milli ohms. 1mOhm x 400amps = 0.4V and I2R = 160watts.

Re: Electric repower Hunter 450 Passage

I only tested to just under 10kW. When I go over 10kW the voltage at the sensor for the generator starts to fall as more and more current comes from the batteries. When the voltage drops to < 48V...
