Good To Know

Q: Can this relay be used with a different brand of outboard? A: It is specifically designed for the Yamaha models listed, but it may be compatible with other engines if the mounting and electrical connections match, so always verify with your engine's specifications.

Q: What are the symptoms of a failing solenoid relay? A: A common symptom is a single clicking sound when turning the key, but the starter motor does not turn. Another sign is intermittent starting, where the engine only starts after multiple attempts.
