Replace your boat’s riser with a MerCruiser 5.7 riser kit (or riser kits for 5.0L and 6.2L engines) from NuWave Marine. We have decades of experience providing parts and knowhow to mechanics and boat owners who need to maintain and repair their engines. One thing is for certain, replacing worn parts before they cause big problems is key to keeping your engine healthy and your boat on the water. We recommend inspecting your exhaust every year and replacing it completely every 5 years for saltwater applications. Freshwater parts might last longer, but they’ll still need routine maintenance. Combined with other MerCruiser exhaust parts for 5.0, 5.7, and 6.2 engines, our riser kits will help you keep your boat on the water, year after year.
MerCruiser 5.7 Exhaust Riser
The exhaust riser needs to sit at an elevation that prevents water from back flowing up the exhaust and entering the engine. It also needs to form a perfect seal with the manifold to make sure that cooling water doesn’t enter the combustion chamber. If you need an individual MerCruiser 5.7 exhaust elbow, you can find it here. For complete replacement kits, check out NuWave Marine’s MerCruiser 5.0, 5.7, and 6.2 exhaust kits.
MerCruiser 5.0 Exhaust Riser
MerCruiser 5.0 riser replacement is crucial maintenance, but you need to inspect other parts as well. Just one faulty gasket can lead to a catastrophic leak, so it’s important to check every component, no matter how small. If there’s a crack, corrosion, or damage to the seal area on your manifold, you’ll have to replace that as well. Luckily, NuWave Marine also carries MerCruiser exhaust manifolds for 5.0, 5.7, and 6.2 engines.
MerCruiser Replacement Parts You Can Trust
Unfortunately, not all replacement parts are created equal. As marine mechanics, we’ve seen the kind of damage that off-brand parts can do, which is why we only carry the very best. In our selection, you’ll find premium OEM parts straight from the manufacturer, and elite aftermarket parts from other brands that meet our high standards for durability and longevity. If you have any questions about what part is right for your exhaust, don’t hesitate to contact our team today.
