These Holley Model 4175 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 typical Model 4175 quality all the way, with a spread bore flange, vacuum secondaries, single fuel inlets, an electric or manual choke (your choice!), 30cc accelerator pumps, and a 5 in. airhorn (unless otherwise noted).
