Trim fuse keeps blowing.

[vermontsmallengine]

I have a 1989 Sea Ray 200 Cuddy Cabin. The 20 amp trim fuse keeps blowing. I replaced the fuse and holder thinking holder was old and needed replacing anyway. That didn't seem to fix the problem. It doesn't blow all the time, but at least once or twice in the trip out. The trim pump sits under removable seat where you step to get in the boat from the ladder. With water coming off you when stepping in the boat and possibly landing on trim pump could that blow the fuse?

Fuse blows from something drawing to much current. In this case the most likely item is the pump motor. Might fix it by taking it apart and cleaning, or send it out for rebuild/cleaning. Moisture and electric motors don't work well together
