Installation Guide
- Safety First: Trailer the boat and disconnect the battery to prevent accidental operation of the trim system.
- Secure the Outdrive: Raise the outdrive to its highest position and engage the trailer lock or use a suitable block to support its weight.
- Access the Trim Rams: Locate the two power trim cylinders connecting the transom assembly to the outdrive.
- Remove Anchor Pins: At the upper end of each trim cylinder, remove the E-ring (clip) from the anchor pin.
- Extract Old Components: Carefully tap out the anchor pin and remove the old end cap and bushings from the cylinder eye.
- Clean and Inspect: Clean the cylinder eye and the anchor pin, inspecting for any damage or excessive wear.
- Install New Bushings: Insert the new bushings and end cap into the trim cylinder eye.
- Reassemble: Re-insert the anchor pin through the new bushings and secure it with the new E-ring.
- Repeat: Perform the same steps for the second trim cylinder.
- Test Operation: Lower the outdrive, reconnect the battery, and test the power trim system for smooth, leak-free operation.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my MerCruiser outdrive?
A: This kit is specifically for MerCruiser Alpha One Generation II sterndrives, model years 1991 to present. You can verify fitment by matching the part numbers listed (e.g., 53-815949, 23-815950) with those in your service manual or by checking the exploded parts diagrams for your drive's serial number range.
Q: What are the signs that my trim ram bushings are failing?
A: Common symptoms include excessive play or "slop" in the sterndrive, difficulty maintaining trim position, or visible hydraulic fluid leaks around the trim cylinder anchor pins. Worn bushings can compromise the alignment of the trim rams, leading to further damage.
Q: Does this kit include the washers?
A: The kit contains all core components (E-rings, bushings, caps). However, the inclusion of washers (Part No. 12-815952) can vary. We advise checking the specific contents of your package upon receipt as noted in the "Package Contents" section.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details.
