MerCruiser 3.0 Exhaust Parts

NuWave Marine carries a full line of OEM MerCruiser 3.0 exhaust parts, as well as high-quality aftermarket options from Sierra. Whether you’re replacing a single component or doing a complete rebuild, we’ve got the parts you need to get your engine running at max capacity and efficiency.

Exhaust system failure can lead to devastating damage to your engine. At NuWave Marine, we’ve seen our fair share of busted boat engines, and we know the best way to fix a problem is to prevent it from happening in the first place. For this reason, we recommend changing OEM exhaust parts at least every 5 years for salt water boats. For fresh water applications, we’ve seen parts last for up to 10 years, but it’s still smart to inspect them regularly. Should you need replacement parts, you’ve come to the right place.

MerCruiser 3.0 Exhaust Manifold

Premium MerCruiser exhaust manifolds from NuWave Marine come complete with gaskets, pipe plugs, fuel line, and mounting hardware. If you’ve noticed leakage around the gaskets of your manifold, the safe thing to do is to replace the entire unit. Precision-engineered for performance, both OEM and Sierra manifolds should last for years.

MerCruiser 3.0 Exhaust Riser and Riser Elbows

Risers and riser elbows are other key components of your exhaust system, and just like your manifolds, need to be inspected often and occasionally replaced. With new MerCruiser risers you can be sure your MerCruiser 3.0 performance exhaust will do its job, whether you’re chasing down a school of striped bass, or enjoying a leisurely cruise.

Smaller replacement parts are also integral to routine engine and exhaust system maintenance. MerCruiser exhaust gaskets and MerCruiser Y pipes and down elbows can also be found in our comprehensive inventory of MerCruiser 3.0 exhaust parts. It’s true that an ounce of prevention is worth a pound of cure, especially when it comes to boat engines. Perform regular inspections and replace parts before they become a big problem. Your boat will thank you for it.
