Holley 4160 Marine Carburetors

Holley 4160 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 are designed to meet flooding and backfire requirements as defined by the U.S. Coast Guard. Other than that, they're typical Holley quality all the way, with a square bore flange, vacuum secondaries, single or dual fuel inlets, an electric or manual choke, 30cc accelerator pumps, and a 5 in. airhorn (unless noted otherwise). And last but not least, you can choose between universal or direct fit OE replacement versions. Show Less
