Hi all,

I'm building a large barge (60” by 30”) and its going to weigh in the neighborhood of 47lbs. I have two 12v motors I’m planning on using to power it 1/4 hp, 1800 RPM, at 21amps. I’m having trouble finding a speed controller for that motor that will allow revercing.

I’ve been toying with the idea of using resistors and a slide (similar to old slot car controllers) have any of you done this sort of work?

Also what sort of motors do you all run in your larger boats?
