Good To Know

Q: How do I know if this gasket fits my watercraft? A: Confirm your model runs the 1503 engine and that your existing part cross-references to 420430624. Checking your serial number against a parts diagram is the surest way to verify.

Q: Should I replace this gasket during a rebuild? A: Yes, gaskets compress over time and reusing an old one can lead to leaks. Fitting a fresh cam chain plug gasket during rebuild or resealing is standard practice.

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