- For safety, disconnect the boat's battery to prevent accidental operation of the trim system.
- Remove the old nuts and washers securing the existing front anchor pin.
- Carefully drive out the old pin to free the trim cylinder from the transom mount.
- Clean the mounting area on both the transom assembly and the trim cylinder eye.
- Align the trim cylinder with the transom mount and slide the new anchor pin into place.
- Secure the new pin with the provided washers and nuts, tightening to the manufacturer's specified torque.
- Reconnect the battery and cycle the trim system several times to confirm smooth, correct operation.
Troubleshooting & FAQ
How do I know this is the correct pin for my trim ram?
This pin is for the front mounting position of the trim rams (the one closest to the transom) on Mercruiser R/MR/Alpha One drives from 1983–1990. The rear anchor pin is a different part. Always verify your sterndrive's serial number and compare your old part to our photos to ensure an exact match.
What are the signs of a failing anchor pin or bushings?
Common symptoms include excessive play or "slop" in the sterndrive when tilted, audible knocking sounds during trim operation, or visible corrosion and wear on the pin itself. Degraded or missing rubber bushings are also a clear indicator that replacement is needed.
Can I just replace the bushings instead of the whole pin assembly?
While bushings can be a failure point, wear often occurs on both the pin and bushings simultaneously. Installing new bushings on a worn or corroded pin can lead to premature failure. This kit provides all necessary components for a complete and lasting repair.
