Troubleshooting & FAQ

How do I confirm this relay fits my specific engine model?

The best method is to match the part number from your old relay to the numbers listed in our "Part Number Cross-Reference" table. Additionally, review the "Compatible Engine Models" section and use our linked serial number guides to verify your engine series. If you are still unsure, contact us with your engine's make, model, and serial number.

What are common signs of a failing power trim tilt relay?

Common symptoms include the trim/tilt system working in one direction but not the other, a clicking sound from the relay with no motor action, or the system not working at all. Sometimes, the motor may run continuously, which also indicates a faulty relay.

Is this a single relay or a set of two?

This listing is for a single SPDT (Single Pole Double Throw) relay. Most trim/tilt systems use two of these relays—one for "up" and one for "down." It is often recommended to replace them in pairs.
