Troubleshooting & FAQ

Q: How do I confirm this relay fits my engine?
A: The best way is to match your existing part number to one of the numbers listed in our "Part Number Cross-Reference" table. Additionally, review the "Compatible Engine Models" table to ensure your engine's make, model, HP, and year range are listed.

Q: What are the common signs of a failing power trim relay?
A: Symptoms of a bad relay include hearing a clicking sound when you press the trim switch but the motor doesn't move, the trim working in only one direction (up or down), or intermittent operation. Sometimes, corrosion on the terminals can cause these issues as well.
