Minn Kota Trolling Motor vibration

[SoonerSlim]

I have two identical Minn Kota 65Ta clamp mounted trolling motors. Both motors vibrate severely at high speeds. I've checked the armature shafts, the pins, the props, and under the props for fishing line. I've even put on brand new props. Everything checks out OK. I've also talked to trolling motor repair technicians and to Minn Kota customer service. They have no solutions. Anyone else experiencing this problem and did you find a fix?

Re: Minn Kota Trolling Motor vibration

I’ve got a 10 year old Minn Kota that was vibrating bad. My trolling motor hit so many rocks and logs that pin broke in half. I tried to replace the pin with a nail (yes, I am cheap). Finally I bought a new prop with a new pin and it runs like brand new. Did you get a new pin that fits very snug on the prop. The prop should not have any play at all. That’s about all that I can come up with.

Big Al,<br /><br />Yes, I put in a factory new pin and prop. It fits very tight.

SoonerSlim,<br />I have a brand new Minn Kota 55 lbs thrust, 12volt, hand controlled motor. It vibrates under certain conditions. I have used it three times so far and found that if I am going against a strong current it will vibrate between 75 and 100%. My motor is a bow mount and not dead center. It is off to the right side. I haven't talked to the shop yet. It hasn't been a real problem for me. When i talk to the shop I will let you know what they say. One guy I fish with said it vibrates because of the flexible shaft on the later models. Also the depth that you have the motor set at. I fish in about 2ft of water so my motor is running very shallow. Almost cavitating but not so.<br />Post any information you come up with. I am interested.<br />jimpittman
