Get high-quality MerCruiser 5.7 exhaust manifolds (as well as manifolds for 5.0L and 6.2L engines) and other replacement parts you can trust from PowerBoatSupply.com. Your boat’s exhaust is a key system that needs to function properly to keep your boat running like it should. Even a little bit of water seepage in the exhaust can cause major problems down the line, which is why PowerBoatSupply.com recommends that you inspect your exhaust yearly, and replace the whole thing every 5 years for saltwater applications. Freshwater exhausts might last longer, but it’s still smart to keep a vigilant eye on the components. Whether you need MerCruiser 5.7 manifolds, risers for a 5.0L engine, gaskets for your 6.2L motor, or any other component, we have the MerCruiser exhaust parts for 5.0, 5.7, and 6.2 engines that you need.
MerCruiser 5.7 Intake Manifold
The manifold is the part of the exhaust that fits on top of the cylinders of your engine and feeds hot gasses into the riser elbow. Manifolds are also a place where water circulates to cool engine exhaust and can be a point where a parts failure (even if it’s just a gasket) can lead to water entering the piston chamber. If you notice something wrong with your manifold, you might need a MerCruiser 5.7 exhaust manifold kit that also contains the gaskets and bolts you’ll need to connect your manifold to the adjacent parts while forming a watertight seal. Consider buying MerCruiser 5.0, 5.7, and 6.2 exhaust kits if you think you need to replace your entire exhaust.
MerCruiser 5.0 Manifolds and More
Whether you need a MerCruiser 5.0 manifold (or 5.7 or 6.2 manifolds) or MerCruiser 5.0, 5.7, and 6.2 riser elbows, you’ve come to the right place. PowerBoatSupply.com has been supplying marine mechanics and boat owners with high-quality replacement parts since the 1980s. We know how important even the smallest part can be, which is why we only carry the best OEM parts and choice aftermarket parts that meet our high standards for durability, longevity, and performance. If you have any questions about what parts you need for your engine, don’t hesitate to contact our staff today.
