My 2005 55lb bow mount when at max power starts to turn on and off on and off continuously which really shakes the mount is this normal what is wrong? Only does it at Max power

[katoguy]

Definitely not normal. Since it only happens on high power I initially am thinking that maybe you have a circuit breaker kicking on/off??? If the problem is in the motor, then it would be a defective main control board.

Check the breaker, then take the motor in to a Minn Kota warranty center.

I would check all connections from the battery to the motor. I would think one is disconnecting intermittently.

I concur. I had experienced the same problem with my 40pd when I first got it. I only had a 40A circuit breaker but the motor was rated for 42A so I had to upsize to a 50A circuit. Be careful here. If the wire from the battery to the motor are not sized for the load current, you could overload them by upsizing your circuit breaker and have a fire potential.

If you didn't have this problem in the past but now it has become an issue, I would suspect that the circuit breaker is fine but something in the motor is causing excessive load. Could be anything that causes the motor to turn hard. Have you removed the prop and checked that nothing is wrapped up on the motor shaft? How old is the system? Could be the motor is wearing out or a motor shaft bearing/bushing is going bad.

I have a 55 to, I've only used a couple of times. I've been having the same problem (circuit breaker tripping) when I run the motor wide open for several minutes. i talked the the guy that sold me me the motor and he said that it was normal. I'm not sure I believe that. Last night when I was charging the battery I found a connection on the breaker that was loose ( I could turn the nut with my fingers) I tightened it, it remains to be seen it this will solve the problem or not.

I am simply amazed by this web site. No matter what your problem or question is you can get some advice here.

You get good advice because we all run across a lot of the same problems. But this is the place to get your info.

sound's like your main board is going out, happened to my 74lb. maxxum twice. needed rubber spacers between carpet and foot pedal to let air in to cool off board it was getting hot and burning it out.

If u have a 40amp circuit breaker, change it to a 50Amp. I had a same symptom with my prev #55.
