These 4150 marine carburetors include all of the same features as their street cousins--plus a few more that make them adaptable and legal for marine use. Primary differences include fuel bowl vent tubes, sealed throttle shafts, and universal marine calibration. Plus, they're designed to meet flooding and backfire requirements as defined by the U.S. Coast Guard. Other than that, they're signature Holley quality all the way with mechanical secondaries, square bore flanges, a manual or electric choke, dual fuel inlets, 30cc or 50cc accelerator pumps, and 5 in. airhorns (except where noted).
