Durable and designed to last. Circulates water around the pump motor housing, helping to absorb the heat given off by the operating motor. The bilge pump is secured directly to the hull - no bracket required. The aerator pump is available with a 3-1/2" long inlet for fiberglass hulls. Pump housings are made of a rugged, glass and mineral-filled polymer that withstands hull pounding and resists chemicals - not just fuel, oil and detergents that accumulate in the bilge, but also the plasticizers used in most hoses. 3/4" barbed inside diameter.
