Building on the trusted performance and durability of the Aluminum Street Avenger Series, we've designed our new marine models to carry on the legacy that Holley is famous for. These all-aluminum carburetors feature a hard coat anodized finish in a sleek Hard Core Gray, ensuring they stand up to corrosion whether you're in fresh or saltwater. The Marine Avengers are engineered to surpass Coast Guard standards and proudly hold the J1223 Marine Standard certification.

Whether you're planning a leisurely day on the lake or seeking some high-speed excitement, the Aluminum Marine Avengers are ready to meet your performance expectations and then some!

Just 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 life of the product, covering parts, and offering one year of repair labor. After the first year, standard rates will apply for any repair labor needed.
