Speedseal Quick Release Cover

Cooling pump impellers can fail at any time and easy rapid replacement can sometimes be vital to boat safety. Speedseal offers a quick easy inspection and impeller replacement cover for most of the common raw water pumps on the market. The 112 grade naval brass used on these covers is 5mm thick with O-ring channel and recess equal to gasket originally used to guarantee correct space for impeller rotation. The kit comes with only four bolts as the seal is now inside the bolt circle, the other holes can be ignored. These four bolts are of a large diameter with knurled edges that allows them to be hand tightened with no need for extra force to give a perfect seal.
