CMI's Gen-X Headers are a direct factory replacement for Mercury Racing HP525EFI, HP600SCi and HP700SCi engines.
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.

Cyclone "Shorty Header" Replacement Header For Gil Marine, Mercury Hi-Performance & Rex Power Torque Manifolds Fully Polished Finish
Do your performance manifolds look like these but your stainless steel tailpipes still look like jewelry? This is a common problem with a number of aftermarket high performance exhaust manifolds, the solution is to replace them with the Cyclone "Shorty"! An all 316L stainless steel header designed as a direct bolt-on replacement for your cast aluminum manifolds.
By retaining your existing stainless steel tailpipe or riser, you can remove your existing manifolds and simply slide the new "Shorty Header" into place and connect your existing tailpipes. These units are currently available to replace Mercury Hi-Performance, Gil Marine, and Rex Marine Power Torque manifolds. Each header is manufactured to the highest quality standard using 100% 316L stainless steel construction, laser machined flanges for a perfect gasket seal, and exhaust tubes that are B.T.B. bent to exact tolerances every time. A fully welded computer designed water inlet manifold assures equal water flow to each individual exhaust tube. These headers are completely annealed to maximize durability while preventing corrosion. CAD-5 technology was used to develop the staggered length exhaust tube runners which provide for broader low and mid range torque, while yielding incredible peak power. Every kit comes complete with all necessary attaching bolts and gaskets so you can rest assured that you’re getting everything that you need.
Big Block Chevy 10 qt. Stern Drive / Inboard Performance Oil Pan - With Pick-Up
Marine oil pans are subject to special conditions. Closed engine compartments create a lack of air flowing around the oil pan causing higher oil temperatures, which can destroy the lubricating properties of the oil in low capacity pans. The motion of the boat in the water sloshes the oil in pans that don't have correct baffling. Air is ingested through the oil pick-up resulting in momentary loss of oil pressure. The oil is tossed into the crank, which foams and aerates it. The pounding effect of oil in the pan cause fractures in pans without reinforcement.
The design and construction of Hardin Marine oil pans insures there are no problems, even in the roughest conditions. Here are just a few of the Hardin Marine oil pan features:
These oil pans offer a value unsurpassed in the marine industry today.
WARNING Don't be fooled by twenty year old technology that requires you to replace engine main fasteners to install your windage tray. All Hardin Marine pans use state of the art pan mounted windage tray systems offering you the future in oil control.
