Marine Flame Arrestor

The K AND N ENGINEERING marine flame arrestor (model 59-2030) is an essential safety component for any gasoline-powered boat with a carburetor or fuel injection system. Backfire events—whether from improper ignition timing, rich fuel mixture, or sudden throttle changes—can ignite fuel vapors inside the engine intake manifold, creating serious fire hazards on the water. A reliable flame arrestor acts as your first line of defense, suppressing these dangerous flame events before they propagate into the engine compartment or cabin, making it a non-negotiable upgrade for serious anglers and boaters who prioritize vessel safety.

This marine flame arrestor features a 3-inch inlet with a 5.25-inch outer diameter and stands 6 inches tall, engineered for direct installation on standard marine carburetor vent lines and intake systems. The 3¾-inch mounting flange provides secure, vibration-resistant fastening in tight engine compartments common on center consoles and cabin cruisers. Constructed from polished stainless steel, this unit resists saltwater corrosion and maintains structural integrity even in harsh marine environments where moisture and spray are constant threats. The arrestor's internal mesh design traps and cools flame fronts instantly, preventing fuel-air mixtures from igniting while maintaining unrestricted airflow for proper engine breathing and fuel system venting.

Boaters restoring vintage carbureted engines, retrofitting older vessel propulsion systems, or upgrading safety on high-performance offshore rigs benefit most from this marine-grade flame arrestor. Installation is straightforward on most inboard and outboard platforms where carburetor ventilation routes through engine compartments. The polished stainless construction ensures this arrestor remains corrosion-free for years of salt-water exposure, requiring only routine inspection to confirm mesh integrity. Compliance with USCG and ABYC marine safety standards makes this component ideal for vessels requiring certified fire suppression equipment for insurance and operational peace of mind.
