FLAME ARRESTOR RAPTOR 6.2 MODEL 360, 400, 440, AND 575

Indmar Marine Flame Arrestor – Ford 6.2L Engine | Part #525900

A critical safety component that should never be overlooked — this genuine Indmar flame arrestor is designed specifically for the Ford 6.2L marine engine. Unlike a car engine which uses an air filter purely for filtration, a marine flame arrestor serves a vital safety function — preventing engine backfire from igniting fuel vapours in the engine bay and causing a potentially catastrophic boat fire.

Compatible with: Indmar Ford 6.2L marine engines fitted to Malibu, Moomba, Supra, and Tige boats.

What does a flame arrestor do?
In a marine environment, fuel vapours can accumulate in the enclosed engine bay — creating a serious fire and explosion risk. The flame arrestor sits on top of the carburettor or throttle body and:

• Prevents backfire flames from escaping the engine intake
• Stops ignition of fuel vapours in the engine compartment
• Allows clean air flow into the engine for combustion
• Meets Australian and international marine safety standards

This is not optional equipment — it is a legal requirement. Operating a marine engine without a functioning flame arrestor is illegal under Australian maritime regulations and will void your insurance.

When should you replace it?
Inspect your flame arrestor every season. Replace immediately if you notice:

• Visible damage, dents, or crushed mesh
• Heavy carbon build-up that can't be cleaned
• Corrosion or rust on the mesh element
• Any backfire damage or heat discolouration
• Loose or damaged mounting

How often should you clean it?
Remove and clean your flame arrestor at every service using a degreaser and compressed air. A blocked flame arrestor restricts airflow to the engine, reducing performance and fuel efficiency. If cleaning no longer restores airflow — replace it.

Pro tip: A restricted flame arrestor is a surprisingly common cause of poor performance and fuel economy on the Ford 6.2L — before spending money on diagnostics, check and clean your flame arrestor first. It's one of the quickest and cheapest fixes available.
