So im going across the lake and all of a sudden my motor starts trimming itself up. I push the switch to trim it down and it stops trimming up but will not go down. I let off the switch and the motor continues to raise by itself until its trimmed all the way up. With the key off the only way to stop the trim motor from running was to disconnect power from battery. The trim switch on the motor does the same thing. It will stop trimming up when pushed down but when released continues to trim up on its own. Has any one encountered this. Thanks daniel
