MerCruiser 5.7-5.0-6.2 Exhaust Parts
PowerBoatSupply.com carries a full inventory of replacement MerCruiser 5.7, MerCruiser 5.0, and MerCruiser 6.2 exhaust parts to help you keep your boat’s engine running at peak condition.
Since 1987, we’ve been helping boat owners and mechanics maintain and repair their MerCruiser engines. From experience, we’ve learned that routine inspection of exhaust system parts is the best way to identify small problems before they lead to major engine failure. We carry a full selection of OEM and aftermarket parts, including 5.0-5.7-6.2 exhaust kits, which have all the parts you need to do a complete overhaul. If you notice corrosion or a leak, or it’s been over 5 years since your salt water boat’s exhaust was last replaced, the right move is to replace your current components with new ones.
MerCruiser 5.7 Manifold and Riser
For 5.7L engines, PowerBoatSupply.com has got you covered. Our full inventory of 5.0-5.7-6.2 manifolds includes MerCruiser 5.7 manifold replacement kits. The function of the manifold is to take spent gas from each cylinder and vent it into the exhaust system. A leaky gasket here or there could let water seep into your motor, thus destroying it. Keep a keen eye out for anything that looks out of the ordinary, and replace parts if necessary.
MerCruiser 5.0 Exhaust Parts
With new parts from PowerBoatSupply.com, your 5L engine will be humming like a classic Mustang. Find riser elbows, Y pipe parts, space kits, and other key components like bolts, bellows, and gaskets.
MerCruiser 6.2 Exhaust Manifolds
If you need to redo the exhaust system on your MerCruiser 6.2 engine, you’ve come to the right place. Just like with the 5.7L and 5.0L, we have the parts you need to fix minor exhaust problems quickly. Should you need an entire new manifold, we have those too.
For over three decades, PowerBoatSupply.com has supplied repair shops and individual boaters with the components they need to rebuild MerCruiser engines. From MerCruiser 5.7 exhaust spacer kits to transom assemblies, outdrives, and other engine parts, we’re here to help you spend less time in the shop and more time on the water.
