Troubleshooting & FAQ

Q: How do I confirm this switch fits my Mercury or Mariner outboard?
A: Check your existing switch for the part number stamped on the housing. If it matches 87-18286A43, 87-16991A1, 87-18286A2, or 87-18286A26, this replacement will fit. You can also consult your engine's parts diagram using the Mercury Parts Catalog link above.

Q: The tilt/trim isn't responding after I installed the new switch. What should I check?
A: First, ensure the wiring connector is fully seated and locked. Verify the battery is reconnected and fully charged. Check the fuse in the tilt/trim circuit and inspect all wiring for corrosion or damage. If the issue persists, test the tilt/trim motor and pump independently to rule out other system faults.

Q: Can I use this switch on both tilt-only and tilt-and-trim systems?
A: This switch is designed for engines equipped with power tilt and trim systems. Verify compatibility with your specific remote control model and wiring configuration before purchasing.

Q: How often should I replace the tilt trim switch?
A: Replace the switch when you notice intermittent operation, no response when pressing the switch, or physical damage such as cracks or corrosion. Regular use in marine environments can wear contacts over time, so inspect periodically for signs of failure.
