Mercury Sea Pumps - Mercury Generation 4 Sea Pump Assemblies

Stainless Steel Sea Pump Assembly

Finally a Sea Water Pump designed to last a life time. Hardin Marine has taken their years of sea water pump manufacturing experience and designed an all new stainless steel water pump to replace the factory pot metal and plastic style pumps used on original equipment applications.

These pumps are cast from 316L high quality stainless steel and each pump uses a double roller bearing style snout assembly while integrating a one piece rear impeller housing. These housings will not crack and erode like the factory style units. A factory style press on pump mandrel can be used to accommodate most pulleys. A unique feature to this pump is that the rear housing has 1"npt female inlet/outlet ports so that a wide range of fittings and hose connections can be used for ease of installation.

If your looking for what could possible be the last sea water pump you ever buy look no further as this is the finest direct replacement sea pump on the market today.
