Installation Guide

1. Ensure the engine is off and the stern drive is tilted to a safe, accessible position to relieve pressure on the trim rams.
2. Carefully remove the old or broken anchor pin cap. You may need to gently pry it off if it is stuck.
3. Clean the area around the anchor pin, removing any debris or fragments from the old cap.
4. Align the new anchor pin cap with the pin head.
5. Firmly push the new cap onto the anchor pin until it snaps securely into place. Do not use excessive force, as this can damage the cap.
6. Visually inspect the cap to ensure it is fully seated and not loose.
7. Cycle the trim system up and down several times to confirm the cap stays in place and functions correctly under load.
