Good To Know

Q: What causes marine exhaust manifolds to fail? A: Corrosion from salt or raw water over time is the leading cause of internal wall failure, which can let water enter the engine.

Q: Does this manifold include mounting gaskets and hardware? A: Please check the specific package details, as mounting hardware and gaskets are typically sold separately.

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