Troubleshooting & FAQ

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

A: The best way is to compare your old part number to those listed in our cross-reference table. Additionally, check the Compatible Engine Models table for your engine's brand, HP, and serial number range if available. When in doubt, visual comparison with the product photos is a helpful final step.

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

A: Common symptoms include the trim/tilt motor working in only one direction (up or down), a clicking sound from the relay with no motor action, or the system not working at all. Sometimes, the motor will run continuously, which also points to a faulty relay.

Q: Is this a single relay or sold as a pair?

A: This listing is for a single relay. Many trim/tilt systems use two relays (one for "up" and one for "down"). If you are troubleshooting a complete system failure, it is often recommended to replace both relays at the same time.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?

A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
