The best way to confirm is to check the compatibility tables on this page against your engine's model, horsepower, and year.

It's recommended to replace the seals whenever you perform major service on the lower unit, if you notice any signs of a leak, or if the boat is used heavily in saltwater or commercial applications.\u003c\/p\u003e\n \u003c\/details\u003e\n \u003cdetails\u003e\n \u003csummary\u003eCan I reuse this seal if I remove the propeller shaft for other maintenance?\u003c\/summary\u003e\n \u003cp\u003eNo. Oil seals are designed for a single installation. Once removed, they can become stretched or damaged, and will not provide a reliable seal if reinstalled.

Is the relay the problem?\u003c\/summary\u003e\n \u003cp\u003eThis is a classic symptom of a failed relay. Power trim systems use one or two relays to reverse the motor's polarity. If it operates in one direction, the motor is likely fine, but the relay has failed on one side of its internal switch. Replacing the relay usually solves this.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n \u003csummary\u003eIs this a single relay or do I need two?\u003c\/summary\u003e\n \u003cp\u003eThis depends on your system. Some older or simpler trim systems use a single relay, while many use a pair of identical relays (one for up, one for down). Check your engine's service manual or inspect the existing setup. If you see two identical relays side-by-side, it is best to replace them as a pair.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n \u003csummary\u003eOEM vs. Aftermarket?\u003c\/summary\u003e\n \u003cp\u003eThis listing is an aftermarket replacement (not OEM).
