Protect your PCM 6.0L gasoline inboard engine and help meet marine safety requirements with this stainless steel mesh flame arrestor. Designed for marine intake systems, it helps stop an intake backfire flame from traveling outside the throttle body/carburetor area—reducing the risk of igniting fuel vapors in enclosed engine compartments. It’s an essential safety component for reliable boating operation and a smart replacement when your current arrestor is clogged, corroded, or damaged. Built for harsh marine environments, the corrosion-resistant metal housing and tightly woven stainless mesh are engineered to withstand moisture and exposure typical of inboard engine bays. Ideal for routine maintenance, restorations, or replacing missing/incorrect intake safety equipment on compatible PCM 6.0L setups. Fits: PCM 6.0L gasoline marine engines (inboard applications) Purpose: Arrests intake backfire flames to help reduce fire risk Material: Stainless-steel wire mesh with durable metal rim/housing Placement: Engine air intake / throttle body or carburetor intake (by application) Best for: Replacement flame arrestor during service, repairs, or safety compliance checks Fitment Notes Please confirm compatibility with your specific PCM engine model/year and intake configuration before ordering. For the best match, compare your existing flame arrestor dimensions and mounting style, or share your engine serial number and current arrestor measurements. FAQ Is a marine flame arrestor the same as an automotive air filter? No. A marine flame arrestor is designed to prevent flames from exiting the intake during a backfire. Automotive filters focus on particulate filtration and are not a substitute in marine gasoline inboard applications. When should I replace my flame arrestor? Replace it if the mesh is clogged, dented, damaged, heavily corroded, or if you’re bringing an older setup back to proper marine safety standards.
