Building on the reliable performance and durability of the Aluminum Street Avenger Series, we've crafted the latest marine models to carry on the legacy that Holley is renowned for. These all-aluminum carburetors feature a Hard Core Gray anodized finish, designed to shield them from corrosion whether you're in fresh or saltwater.

The new Marine Avengers are engineered to surpass Coast Guard standards and hold a J1223 Marine Standard certification. Whether you're taking a leisurely cruise on the lake or seeking some high-speed thrills, you can trust that the Aluminum Marine Avengers will rise to the occasion and meet your performance expectations!

When it comes to peace of mind, the Marine Avenger Carburetors come with the same Limited Lifetime Warranty as our Street Avengers. Holley guarantees that your Marine Avenger Carburetor will be free from defects in materials and workmanship for the life of the product, covering parts and one year of repair labor. After that, standard rates will apply for any repair labor needed.
