Installation Guide
- Ensure the engine is off and the stern drive is tilted to a safe, accessible position to relieve pressure on the trim rams.
- Carefully remove the old or broken anchor pin cap. You may need to gently pry it off if it is stuck.
- Clean the area around the anchor pin, removing any debris or fragments from the old cap.
- Align the new anchor pin cap with the pin head.
- 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.
- Visually inspect the cap to ensure it is fully seated and not loose.
- Cycle the trim system up and down several times to confirm the cap stays in place and functions correctly under load.
