TECH TIP:

Late-model Mercury seawater pumps utilize a single-piece plastic water pump housing. While this housing is easy to change, it does not have a desired feature of having a stainless-steel wear plate in the rear. Without the wear plate, the housing is easily damaged by debris and immediately damaged from running dry. Once the housing is scored where the impeller seals on each end, the impeller to housing seal is compromised, which can cause the pump to not draw water when the boat is first launched. If this is the case, the damage increases and the pump could fail completely. The Hardin Stainless steel "Lifetime" Sea Water pump replacement housing kits retrofit your one-piece pump factory Mercury Housings and eliminate old obsolete two piece housings that used corrosive inferior billet aluminum (aftermarket) rear inlet plates Experience and knowledge prove that this “heavy-duty” all stainless steel design survives better in environments where the pump can be contaminated by sand or other abrasive debris.

I installed this pump almost 2 years ago in my 502 Mag MPI Bravo powered Laveycraft. In the past after 1 year, my impeller would be cracked and worn out. The OEM housing would need replaced every 2 years. In the 14 years that I've owned the boat, I've also broke the OEM housing during impeller replacement 3 times, by cracking or otherwise breaking a nipple by dropping it in the bilge or over-tightening the hose clamps, which both are easy to do, in my boat, where I can't see the pump and only can get one hand on it under the engine when installing or pulling it out.

This unit is a finely machined / polished item. Has eliminated ALL problems associated w/ the cheap plastic pumps.
