I have a 1993 Stingray with a MerCruiser 4.3LX/V6 Alpha One motor. "Trim up" button does not do anything or make any noise. "Trim down" clicks/knocks by the trim motor and then works most of the time and "Trailer up" works all the time. The Paul Harvey version ... Last year when I got it out of storage I hooked up the battery backward. It was dark to my defense and the length of the wires matched perfectly. I didn't know it until i smelled electrical smoke in back of engine. It worked somewhat last year ... I used the trim down button and trailer up button to trim up ... but now it drains my battery in couple hours.
I am not an experience boater but don't mind getting hands dirty. It also been nearly impossible to find anyone to work on it.
My initial thoughts is that it's the trim buttons. Since it will trailer up, i was thinking relays/pumps working fine. But I smelled smoke from the back of engine last year.
I did attempt to check for any melted wiring in back ... but didn't see any.
Any suggestions where to start?
