Specs At A Glance

Good To Know

Q: How do I know if my starter gear needs replacing? A: Common signs include a grinding noise during start attempts, the engine failing to crank, or visible wear and missing teeth on inspection. Confirm the fault lies with the gear rather than the starter motor or battery before ordering.

Q: Does this gear require any special tools to install? A: Installation typically involves removing the starter assembly and swapping the gear, so basic hand tools and a service manual for your model are recommended. Follow your watercraft's service procedure for torque values and reassembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
