What is Different About Marine Exhaust Systems?

Marine Exhaust Systems are subjected to abnormally severe operating conditions. The conditions boats operate in include severe temperature variations as well as extreme corrosion conditions that come with salt water. Can you visualize having 1400F degree exhaust temperatures on the inside of the exhaust manifold passage but then having 33F degree water on the water jacket side just 1/4 inch away? For companies like MerCruiser that have a long history (Read More) of producing high quality Marine Exhaust Manifold Products at the best value requires exhaust product designs that utilize dual-wall castings with the appropriate materials, and casting the correct wall thicknesses (normally 1/4 inch thick) and water passage flow areas. The higher quality Marine Exhaust Systems we see today include exhaust manifold and riser designs such as the MerCruiser Dry Joint Exhaust System (Read More).

PPT’s High Quality Marine Exhaust Systems include direct replacement Manifolds, Risers and Spacers that are the marine industry’s only internally and externally double and triple EDP Coated 3 year warranted exhaust systems. PPT offers both traditional Wet Joint and the newer Dry Joint Exhaust Systems. PPT Exhaust products for most MerCruiser engine models are offered in both Aluminum or Cast Iron. These direct replacement Marine Exhaust Manifolds & Risers for MerCruiser are not only designed better but coated to last longer. But here’s the best part…..PPT Exhaust Systems are offered at the absolute lowest prices!

TRIPLE COATED Aluminum Exhaust Products

Our Triple Coated Aluminum Boat Exhaust Manifolds and Risers for MerCruiser Exhaust System applications come standard with a …3 year warranty… versus most OEM’s 1 year warranty, and also come complete with all of the required gaskets (both manifold and riser bolts) and come with all new mounting fasteners and exhaust plugs as well. But, unlike the competitors direct replacement exhaust manifolds and risers that come with only exterior primer paint, our products come with a specially developed DOUBLE EDP COATING + EXTERIOR POWDER TOP COATING that isn’t offered on any other competitive Marine Exhaust Products. Our extensive background engineering products for one of the largest OEM’s in the industry allowed us to gain a tremendous amount of experience which we now apply to our own products and product lines, and therefore offer at a fraction of the cost of the original equipment manufacturers costs.
