Re: Powering a 12 ton boat; need advice on big DC motors
I wonder if instead of one big 12 HP motor,you could use several 12V treadmill motors,I see some rated up to 4.5 HP at the Surplus Center's site ,prices ranging from under $100 to about $200--they are designed for use with variable speed control .
Now there's a good thought. You could mount them on a couple old outboard motors with the gas engines removed.
Separate batteries, separate turning for steering if required, props already in place, forward neutral and reverse, and you could leave the original drive system completely separate for when you are out on open water.
