1992 88 SPL Trim Tilt issue

During the last few outings it seemed like the trim tilt was slowing down a bit. Now in the driveway it responds normally going up in the tilt zone, but not down. There is a little noise at the trim tilt motors (2) but not enough to tell which is trying to run. This setup on a Boston Whaler Montauk 17 seems to have two trim/tilt motors and a relay box mounted on the inside of the stern. Any guidance on how to start troubleshooting this would be appreciated.

OK, speaking before looking hard enough. The thing on the right is the reservoir. judging by rust, it looks like the whole trim tilt assembly has been changed more recently than the actual motor. If the motor still runs in one direction, is it likely that its just a connection in the wiring gone astray?

likely a wiring, relay, or connection problem.  Swap the relays to see if the problem reverses itself.

Bill,

 

Further testing, and then the  motor stopped working at all, just making a tiny little noise once when activated, has led us to obtain a replacement motor. I am hearing conflicting info regarding getting to that one of three screws in the back against the hull. Some places indicate that the whole motor has to come off the boat to get to it, and some that the complete trim tilt unit will come out of the transom bracket for access. Looks like 6 bolts and the piston pin to me to take the whole trim tilt unit out??? And the real answer is???

 

Thanks for your patience with shadetree boat mechanics.

Sometimes you can reach the back trim motor bolt with a 1/4" drive and a flex socket. If the bolt is frozen due to saltwater then then  the whole trim unit has to be removed. With the tilt rod retracted and the 6 bolts removed, the unit can be wiggled free. Sometimes the transom bolts may have to be loosened.
