Installation Guide

1. Disconnect the battery to prevent electrical shock or accidental motor activation during installation.
2. Remove the old trim motor by disconnecting the 2-wire electrical connector and removing the four mounting bolts.
3. Inspect the mounting surface on the tilt/trim unit for debris, corrosion, or damage. Clean if necessary.
4. Install the new O-ring into the groove on the motor housing, ensuring it is properly seated without twists or folds.
5. Position the new motor assembly onto the mounting flange, aligning the bolt holes carefully.
6. Insert and hand-tighten the four mounting bolts in a cross pattern to ensure even seating.
7. Torque the bolts to manufacturer specifications (typically 8-10 ft-lbs) using a torque wrench, again in a cross pattern.
8. Connect the 2-wire electrical connector, ensuring a secure and weatherproof fit.
9. Reconnect the battery and test the trim/tilt function in both up and down directions.
10. Check for leaks around the O-ring seal while operating the motor. If fluid seepage is observed, re-torque bolts or replace the O-ring.
11. Verify smooth operation through the full range of tilt and trim positions under no-load conditions.
12. Perform a final inspection after the first few uses to ensure all connections remain secure.
