Mercruiser Dry Joint Replacement
Replaces 14 degree, Dry Joint "Tall" Riser systems, "Short" 7 degree systems will require custom tailpipes
The term Mercruiser Dry Joint Exhaust refers to a later model (2002 and newer) OEM exhaust system which utilizes 2 coolant passages vs 4, between the manifold and riser that are separated outside of the exhaust gasket.
Manifold is powder-coated for corrosion protection
Optional "Ocean Series" Extreme Corrosion Treatment available for additional interior corrosion protection
Perfect for use on OEM engines up to 400HP
Polished Stainless steel tailpipe is manufactured from premium 316L Stainless steel, 4" OD
356T Aluminum Heat treated tubular style cast internal manifold core for header like performance
Kit includes all bolts and gaskets needed for installation
Risers include O2 Sensor bungs and plugs.
MerCruiser changed their exhaust system design in 2002 by creating a Dry-Joint exhaust system thus removing the cooling water passages from the perimeter of the riser and manifold flange area. Dry-Joint is a proven enhanced design exhaust manifold and exhaust riser compared to standard “Wet-Gasket” style of marine exhaust manifolds and exhaust risers common to early or old style marine industry offerings
