James,
Thanks Eric!
I spent about half the day today searching for connectors, but didn't
run accross Andersons. I'll look them up for sure. I'll have a
difficult time locating them someplace dry unless they are narrow
enough to fit through a small hole in the hull. I've been looking at
plugs and receptacles made specifically for trolling motors, so
they're water tight. I'll figure something out.
I really appreciate the research you did on my motors. I was
wondering how many amps they draw. Technical support at Minn Kota
wasn't much help because the motors are'nt designed for what I am
doing with them. They wouldn't suggest any kind of connector.
I'll be interested in my watts to knots too! I would be very happy
with 4 or 5 knots.
Thanks again,
~James
