Hardin Marine has once again used their racing support and heritage to develop a superior sea pump replacement option for the Mercruiser generation 5/6 application that requires the mechanical fuel pump mounting provision. This pump uses a 316L heat treated Stainless steel snout with a 17-4 hardened pump shaft and high speed roller bearings to provide the ultimate sea pump foundation for years of service.
