Good To Know
Q: How do I know this relay fits my Yamaha outboard? A: Verify your engine's serial number and cross-reference the part number 688-81950-10-00 against your original relay. It is designed for 40, 50, 60, 70, and 90 HP models, but confirming the specific year is recommended.
Q: What are signs that my solenoid relay needs replacement? A: If the engine does not crank or you hear a clicking sound with no starter engagement, the relay may be faulty. Testing the coil resistance with a multimeter can confirm if the relay is within specification.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
