Troubleshooting & FAQ
How do I know if this trim relay is failing?
Common symptoms of a bad relay include the trim/tilt system 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. You can often test it by swapping the 'up' and 'down' relays if your system uses two, or by using a multimeter to check for continuity.
Will this fit my specific engine year?
This relay is designed to fit a broad range of models, as listed in the compatibility tables. However, manufacturers sometimes make mid-year changes. Always verify that your old part's number is listed in our Part Number Matrix and that its appearance matches our product photos.
Is installation difficult?
Installation is straightforward for those with basic mechanical skills. It is a plug-and-play part with standard electrical terminals. However, due to the nature of marine electrical systems, professional installation is always recommended for safety and to ensure correct function.
What's the difference between a trim relay and a starter solenoid?
While they can look similar, they serve different functions. A trim relay directs power to the trim/tilt motor, allowing it to run in two directions (up and down). A starter solenoid is a heavy-duty relay designed to handle the high current required to engage the starter motor for the main engine.
Is this a single relay or a pair?
This listing is for a single (1) relay. Some trim systems use two separate relays (one for 'up' and one for 'down'). Please check your system's requirements before ordering.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
