When it comes to boating safety, having a marine flame arrestor is a must for every boat equipped with a gasoline engine. Holley’s marine flame arrestors not only provide essential protection against the dangers of backfire but also add a touch of style to your vessel. Choosing the right size flame arrestor is crucial for achieving optimal performance; an undersized unit can limit your engine's airflow, much like a clogged air filter would. Holley offers a variety of flame arrestors made from aluminum, chrome, and stainless steel, available in different sizes to fit your needs. Check out the charts below to find options based on their finish, size, and recommended CFM. The CFM recommendations serve as a handy guide to help you select the flame arrestor that matches your carburetor's CFM capacity and fits within your available space.
