MerCruiser OEM Exhaust Kits
PowerBoatSupply.com supplies boat owners and mechanics with MerCruiser OEM Exhaust Kits to replace broken-down exhaust systems or worn-out component parts. We have all the replacement parts you need to get maximum drive and efficiency from your boat engine.
If your exhaust system is functioning properly, you’ll have excellent performance. If there’s a leak, you might end up dead in the water with an engine that needs to be totally replaced. We recommend changing exhaust systems for salt water boats every 5 years, with frequent inspections in between. Any more than 5 years, and you’re making a huge gamble, even if the parts look like they’re in excellent condition. For fresh water applications, parts can last 10 years or more, but it’s still necessary to inspect them often.
If you need to replace your MerCruiser exhaust riser, manifold, or other components like gaskets, bellows, and bolts, search for MerCruiser parts at PowerBoatSupply.com today.
MerCruiser Exhaust Manifold Riser Kits
Though there are some aftermarket parts that are very good quality, we recommend choosing original equipment manufacturer, or OEM, parts whenever possible. PowerBoatSupply.com carries MerCruiser OEM exhaust replacement kits that come with everything you need - including new manifolds and risers - to replace your entire system. When it comes to boat maintenance, the old saying is true; an ounce of prevention is worth a pound of cure. Stop major problems before they occur by preventing leaks, corrosion, and blockages in your exhaust system.
MerCruiser Riser Replacement
From replacement MerCruiser riser elbows to MerCruiser manifolds, we have you covered. Of course, for the time it takes to replace certain parts, it’s sometimes better to just replace the whole system, which is why the MerCruiser exhaust kit is always a popular choice.
PowerBoatSupply.com has been helping professional marine mechanics and DIY boaters find the right OEM exhaust systems and parts since 1987. We know MerCruiser exhausts inside and out, and are happy to answer any questions you may have. We are proud to offer competitive prices and fast shipping on all orders.
