Indmar Marine Flame Arrestor – Ford 6.2L 460 Engine | Part #525902

Keep your engine bay safe with this genuine Indmar flame arrestor, designed specifically for the Ford 6.2L 460 marine engine. A critical safety component that prevents engine backfire from igniting fuel vapours in the enclosed engine compartment — protecting your boat, your passengers, and your investment from the devastating consequences of an onboard fire.

Compatible with: Indmar Ford 6.2L 460 marine engines fitted to Malibu, Moomba, Supra, and Tige boats.

What's the difference between #525900 and #525902?
Both flame arrestors are designed for Ford 6.2L engines — however #525902 is specifically engineered for the 460 variant. Using the wrong flame arrestor can result in poor fitment, restricted airflow, and critically — compromised safety. Always ensure you are ordering the correct part for your specific engine variant. If you are unsure which engine you have, contact us before ordering.

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 throttle body and:

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

This is not optional equipment — it is a legal requirement. Operating a marine engine without a correctly fitted flame arrestor is illegal under Australian maritime regulations and will void your insurance in the event of a fire or accident.

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

• Visible damage, dents, or crushed mesh elements
• Heavy carbon build-up that cannot be cleaned
• Corrosion or rust compromising the mesh
• Any backfire damage or heat discolouration
• Loose or ill-fitting mounting

How often should you clean it?
Remove and clean your flame arrestor at every service using a quality degreaser and compressed air. A restricted flame arrestor chokes airflow to the engine — reducing power, increasing fuel consumption, and creating a safety risk. If cleaning no longer restores proper airflow — replace it immediately.

Pro tip: If you're unsure whether your boat has the 6.2L standard or the 6.2L 460 variant, check your engine serial number or contact us — we'll help you identify the correct part before you order. Getting the right flame arrestor fitted correctly is too important to guess.
