Many Mercury 575HP Motors are still around and still deliver great punch for the cost and cost of running. But some parts are not longer available. The Blower Shop has come to the rescue with a new Billet supercharger option for replacement for the no longer available Mercury 256 supercharger found on all Mercury Racing 575 engines. This new kit includes a direct mount billet supercharger assembly and a greatly improved competition idler system as well as an upgrade main shaft and coupler. The supercharger will accept the factory mounting flange for the throttle body adapter. This supercharger also opens up a limitless pulley options from 2.85″ to 4.35″ for a multitude of boost ranges. A recent install was done by PowerBoatNation Member Biggus on his beautiful 30’ CIGARETTE Mystique
