Marine Wet Exhaust and Dry Exhaust Mufflers
Like other internal combustion vehicles and marine powerplants, inboard engines need a good muffler to perform their best. Marine Parts Source has a large selection of OEM replacement and factory-fit aftermarket marine mufflers to maintain your exhaust system. We carry Centek Industries and Vetus brands so you can find the right muffler for marine applications.
Shop for marine wet exhaust mufflers in many configurations to fit your inboard engine or generator. Whether your boat requires a round straight-through muffler, side-in-top-out muffler, gooseneck water muffler or another design, we’ll make sure you get it. These mufflers are made of durable materials like fiberglass and plastic to handle large amounts of seawater. We also have inboard dry exhaust mufflers for high-performance watercraft along with accessories like thermal shield wrap, hose connectors and drain plugs.
