Holley Gen 3 Ultra Dominator Marine Carburetors

Holley Gen 3 Ultra Dominator Marine carburetors are designed for use on marine high-horsepower engines. They utilize high-capacity fuel bowls with 20 percent more fuel capacity to eliminate starvation, an integrated fuel shelf to minimize fuel aeration, and internal baffling to control fuel slosh. The patent-pending Gen 3 main body is 5/16 in. taller than the previous generation, allowing for larger radius air entries—which are optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturi. Other features include all-aluminum construction, 12-hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points and knurled (hand-adjustable) curb idle screws. Each calibration has been dyno-tested to deliver proven performance! Additional features include: * Gray anodized finish with black anodized billet aluminum metering block and booster inserts * Fully machined from venturi throat to throttle bore for predictable and repeatable performance * Metering blocks feature true gasket sealing and fully adjustable emulsion bleeds, power valve channel restrictors, and idle feed restrictors * Dual 50cc accelerator pumps provide the perfect amount of fuel from idle to full throttle * Clear sight windows on both sides of bowls for easy and safe fuel level adjustments * Built-in drain plug in front center of bowl provides easy access to empty contents of bowl * O-ringed inlet threads offer a large variety of plumbing options and can be plumbed from either side * Factory-ready TPS mounting points for use with data acquisition systems (Holley TPS part number 534-214 available) * Contoured hex head squirter screws for streamlined airflow * Fully adjustable stainless steel external linkage can be adjusted for 1:1 progressive or soft progressive throttle activation (no linkage parts under the carburetor) * J-style vent tubes * 100 percent wet-flow tested by Holley technicians to assure it arrives ready to run
