When it comes to boating safety, having a marine flame arrestor is not just a good idea—it's the law for every boat equipped with a gasoline engine. Holley marine flame arrestors are crafted to shield your vessel from the serious risks associated with backfires, all while adding a touch of style. Choosing the right size flame arrestor is essential for optimal engine performance. An undersized flame arrestor can choke your engine's airflow, much like a dirty air cleaner would.

Holley provides a variety of flame arrestors made from aluminum, chrome, and stainless steel, available in different sizes to fit your needs. The charts below will guide you through the finishes, sizes, and recommended CFM ratings. The CFM recommendations help ensure that you select a flame arrestor that matches your carburetor's capacity and fits well within your available space.
