The Holley R7128 Marine Carburetor is a high-performance fuel delivery system designed specifically for marine applications. This carburetor boasts an impressive 670 CFM (cubic feet per minute) airflow capacity, making it an ideal choice for powerboat engines, outboard motors, and other high-powered marine applications.

The R7128 is equipped with Holley's 4150 series annular boosters, which provide excellent fuel atomization and vaporization. The annular boosters are vacuum secondary, meaning they are activated by vacuum, which helps to maintain proper fuel-air ratio under all operating conditions. This results in improved engine performance, fuel efficiency, and reduced emissions.

The carburetor features a 750 cfm venturi, which is large enough to handle the high airflow demands of high-powered marine engines. The venturi is flanged for easy installation and removal, and it is made of durable, corrosion-resistant materials to withstand the harsh marine environment.

The Holley R7128 Marine Carburetor is also equipped with a powerful accelerator pump, which ensures proper fuel delivery during acceleration. This pump is adjustable, allowing you to fine-tune the carburetor to meet the specific needs of your engine.

The carburetor body is made of lightweight, corrosion-resistant aluminum, which is coated with a durable powder coat finish. This finish is designed to resist fading, chipping, and corrosion, ensuring that the carburetor looks great and performs well for years to come.

The R7128 is also equipped with a removable float bowl, which makes it easy to clean and maintain. The float bowl is designed to hold a generous amount of fuel, reducing the need for frequent refueling during extended use.

In summary, the Holley R7128 Marine Carburetor is a high-performance fuel delivery system that is specifically designed for marine applications. Its large airflow capacity, vacuum secondary annular boosters, and powerful accelerator pump make it an ideal choice for high-powered marine engines. The carburetor's durable construction, removable float bowl, and easy installation make it easy to maintain and use, ensuring that you get the most out of your marine engine.
