MerCruiser Exhaust
If you want maximum performance and long-term reliability from your MerCruiser inboard engine, routine maintenance of your exhaust system is essential. Corrosion and normal wear can damage exhaust components, leading to poor performance or even serious engine issues. At PowerBoatSupply.com, you’ll find a wide selection of MerCruiser exhaust system parts—including exhaust manifolds, risers, bellows, and other replacement parts to keep your motor running at its best. We carry OEM MerCruiser parts as well as trusted aftermarket options from Sierra and other leading manufacturers.
MerCruiser Exhaust Risers
The exhaust riser is a critical component that should be inspected regularly as part of routine maintenance. At PowerBoatSupply.com, we stock the latest designs that efficiently collect hot gasses from the engine and cool them with a water-filled jacket. This process improves exhaust flow, boosts engine performance, and extends the lifespan of your motor.
