Stainless steel seawater pump

Finally, a seawater pump that will last a lifetime. Hardin Marine has used its years of experience in manufacturing seawater pumps to develop an all-new stainless steel water pump to replace the factory metal and plastic pumps used in original equipment.

These pumps are cast from high quality 316L stainless steel and each pump features a double roller bearing snout assembly and a one-piece rear impeller housing. These housings will not crack or erode like the factory units. A factory pump arbor can be used for most pulleys. A special feature of this pump is that the rear housing has 1-inch NPT female threaded inlet/outlet connections, so a variety of fittings and hose connections can be used for easy installation.

If you're looking for possibly the last seawater pump you'll ever buy, you've come to the right place, because this is the best direct-replacement seawater pump on the market today.
