Replace a damaged or corroded flame arrestor
For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and techs can be assured a Sierra part will fit right the first time and restore function.
Flame arrestors are one of the most vulnerable parts of the engine; they are a magnet for boater’s feet as they step into an engine room. They are also more susceptible to corrosion due to heat cycling. Sierra offers a wide selection of flame arrestors to restore appearance and function. Sized for many MerCruiser sterndrive applications, see below for a parts cross reference or visit our engine parts selector to find the right part for your engine or carburetor.
