Fishing yesterday and after deploying the motor for the first time (36v 112), there was no response from pressing the foot switch. Tried engaging the auto pilot from the foot pedal buttons and no response either until after about 4-5 seconds and then the prop would start turning. I turned off the auto pilot, and tried it by manually stepping on the foot switch, and sure enough after about 5 seconds the prop would start turning. It would keep going until I let off the switch, and then the whole process would start over again. Also, when the motor is running I was getting noticeable vibration. It felt like the prop was loaded up with weeds, but it was clean.
I replaced the prop with a brand new one, and this didn't help much, if at all. I noticed that when I spun the prop by hand, nothing felt rough in the motor but the ring where the prop comes into contact with the motor wasn't flush all the way around. Also it seemed like there was way more play than there should have been when I pulled directly back on the prop. I bet the prop assembly would travel a good 1/4" when I pulled on it. I'm guessing the seals and something else in there must be shot.
If anyone has any suggestions on what's going on, I would appreciate it.
