Parts Desk Insights
Best Use Case: Use this thru-hull exhaust fitting when routing exhaust discharge through the hull and you want the flapper to help limit reverse water flow entering the exhaust system and engine when operation conditions change (stopped, slow-speed, or backing down).
Common Issues: Common service points include ensuring the fitting is installed with the correct sealing method for your hull penetration, checking that the flapper moves freely after installation, and inspecting related exhaust components/gaskets during maintenance so the mating areas stay watertight.
