Building on the solid reputation for performance and durability established by the Aluminum Street Avenger Series, we've crafted the new marine models to carry on that legacy that Holley is celebrated for. These all-aluminum carburetors come in a Hard Core Gray finish, which is hard coat anodized to shield them from corrosion, whether you're in fresh or saltwater conditions. Our Marine Avengers are designed to surpass Coast Guard standards and proudly hold the J1223 Marine Standard certification.

If you're planning a leisurely day on the lake or gearing up for some high-speed excitement, the new Aluminum Marine Avengers are here to meet and exceed your performance expectations!

Like our Street Avengers, the Marine Avenger Carburetors come with a Limited Lifetime Warranty. Holley guarantees that your Marine Avenger Carburetor will be free from defects in material and workmanship for the product's lifetime on parts, and for one year on repair labor. After the first year, standard rates will apply for any repair labor needed.

• This carburetor features a square bore flange bolt pattern, allowing it to replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3/16" x 5 5/8" bolt pattern. If your intake manifold is of the spreadbore style, an adapter will be necessary for installation, similar to the Mr. Gasket #1932.
