Howdy. I have a 15' Potter sailboat with a Motorguide 55# as my aux propulsion. probably 1200# gross weight with two peeps. It was a lake boat; out on the bay, 55# is inadequate if there's any wind. I have a motor and shaft from a MinnKota Maxxum 80# bowmount. All I have is the motor, shaft and head (in pieces) There are three leads coming from the shaft... obviously one is positive and one is negative, the other must be for controlling forward, reverse and voltage level for variable rpm. So here's the question guys: help me cheap-out... I have 12 volts on the boat and a 12 volt motor and shaft. Assuming I can sort out a mount, What else do I need to make this motor push the boat? Some type of rheostat to make voltage variable and some type of switch to reverse polarity but I can't visualize the end-game. My desired result is nothing fancy; just need a motor to push straight ahead, shift to reverse, and give me some variable rpm (speed control).
