I have a throttle switch and a switch on the motor. The other day I was running the boat and the motor started trimming up by itself...when I tried to put the motor back down with throttle switch, the motor would stop trimming up but immediately start agian upon releasing the switch. The only way to stop it was to kill the batteries. I trailered the boat, brought it home and began to look for the problem...but it seems to work fine now. I was thinking it was probably one of the switches going bad, but not sure. I don't want to get stranded on the water again with this problem. Any suggestions on how to determine what the problem is?
