Well I took the trolling motor to a shop Saturday and they could find nothing wrong. I actually watched them bench test it and there was no vibration. The pin on the prop was bent so they replaced it thinking it might have thrown the prop out of balance. $35 fee for a bench test. Was a little frustrated at the cost and really nothing done, but they did spend about 15 minutes looking at it so I understand. I get it home and hook it back to the boat, and guess what, yep, it still vibrates.
Could it have something to do with the power supply. It is a 24 volt motor. It turns on and runs fine for about 3 seconds and the then it slows down and starts to vibrate. It noticeably slows down. I can get off the switch and then back on and sometimes it will run smooth, but most of the time it will start to vibrate after a few seconds. Any thoughts?
