Trim Problem

[ciRe]

So I have a 2000 Johnson 50 and had it out the last 5 days and worked flawlessly. However when I was heading home we hit a huge rainstorm. When we stopped in Rolla to eat there was a loud buzz so I went back there to figure out the buzzing sound was my trim going down even with the transom saver on. So I pushed the trim to go up to try to stop it and it went right up and stopped. As soon as I hit trim down it would go down but not stop after I would let go of the button. At first I thought it was maybe a short in the control on the motor but it would do it when I would use the throttle trim button and the other up front. Idk much about boat electronics but any help would be nice. If I need to post a video I can if need be.

Thanks

You have some moisture in the throttle/shift handle switch most likely, or if you have a trim switch at the bow panel it might be that one.

The lower cowling switch is sealed and usually immune to that bug.

Be sure to check the back side of the relay panel. If the motor ran against itself long enough to heat up wires and melt the potting on the back side of the relay panel then you'll probably have some exposed circuits that will eventually corrode and cause you problems later on.

Dry as a can be in there with no signs of old water. Maybe just a relay ? Checked the bow and that was dry also. I even unplugged it and still would trim down without hitting the button.
