Marine Flame Arrestor

The K AND N ENGINEERING marine flame arrestor (model 59-2030) is a critical safety component for any gasoline-powered boat engine. Whether you're running an outboard, inboard, or jet drive, this flame arrestor prevents dangerous backfires and fuel vapors from igniting in the engine compartment—a hazard that can turn a routine fishing trip into a catastrophe. After decades on the water, I've learned that proper engine maintenance includes protecting against the unexpected, and a quality flame arrestor is non-negotiable for serious boaters who value safety and compliance with marine regulations.

This K AND N flame arrestor uses a proven ceramic or sintered bronze element design that allows normal air intake while stopping flame propagation from carburetors back into the fuel system. The compact 6.5 x 7.188 x 6.5 inch form factor and lightweight 1.1 lb construction make installation straightforward on most marine engines without adding bulk or restricting air flow—critical factors when every ounce and inch matter in confined engine bays. The arrestor's durable construction withstands salt spray, moisture, and thermal stress that comes with extended time on the water, ensuring reliable operation season after season.

Boaters running legacy or high-performance engines, tournament anglers, and anyone operating in saltwater environments benefit most from this investment in engine security. Installation typically mounts inline with your carburetor or fuel system intake, and K AND N's engineering ensures compatibility with standard marine engine configurations. If your boat's flame arrestor is missing, damaged, or simply outdated, replacing it with this proven unit is one of the smartest safety upgrades you can make—and it keeps you compliant with USCG and most state marine regulations.
