If you want maximum performance over decades of use from your MerCruiser inboard engine, routine maintenance on your exhaust system is essential. Corrosion, plus the normal wear and tear of use, can damage your exhaust system, which could lead to poor performance and even serious engine problems. At PowerBoatSupply.com, you’ll find a large selection of MerCruiser exhaust system parts, including MerCruiser exhaust manifolds, risers, bellows, and every other replacement part you need to keep your motor in top shape. We carry OEM parts, as well as high-quality parts by Sierra and other leading names.
MerCruiser Exhaust Riser
The exhaust riser is another key component that needs to be inspected as part of routine maintenance. At PowerBoatSupply.com you'll find the latest designs that collect hot gasses from the engine and cool them with a water-filled jacket. The efficient outflow of gasses makes your engine run better and can improve its power and lifespan.
