Good To Know

Q: When should this tensioner guide be replaced? A: It is commonly replaced during any cam chain service or whenever the guide shows cracking, heavy wear, or chain contact damage. Inspect it any time the timing cover is off.

Q: Can this guide be installed without removing the engine? A: Guide replacement is typically done as part of cam chain service, so access procedures depend on the hull and model year. Confirm the service steps for your specific craft before starting.

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