The new design increases water fill keeping the headers full at all time, creating cooler temperatures, which leads to improved longevity and a little extra horsepower.

Featuring more equalized primaries for improved performance, the straight-back headers with downturn collectors work with existing tailpipes and are easy to install. Constructed of quality 316L domestic stainless steel makes for one tough header with a sleek stylish look.

Stainless Steel Gen 7 Sea Pump for Mercury 350, 496 and 502 Mag

For a number of years now the factory sea pumps have been plagued with a design flaw that made each factory pump a throw away non serviceable item. While the impeller could be serviced it is the factory body that wears out prematurely. Without the proper tolerances these units just won’t pump water. Well, Hardin Marine, the largest manufacturer of all Stainless Steel Sea Pumps set out to again solve the short comings of OEM equipment. By developing a stainless steel 316 heat treated casting Hardin Marine was able to incorporate new dual stainless steel serviceable wear plates as well as the use of a standard common Mercury water impeller. These characteristics have now turned this pump into a serviceable replacement that will provide years of serviceable life span. And all at a fraction of the cost of the original pump. So if you’re out to update and upgrade to a pump that's designed to last a life time, look no further as it has arrived. Replaces Mercury #46-862914T08 and #46-862914A2
