4.3 Exhaust Parts
NuWave Marine has a full stock of MerCruiser 4.3 exhaust parts for boat owners and mechanics who need to replace a faulty or worn-out component or take on an entire rebuild. Come to us for all the replacement parts you need to get maximum power from your engine and keep it in top condition.
We suggest changing your OEM exhaust system every 5 years, just to be safe. It’s possible that it could last for longer, but you’re really taking a risk that water will seep into your motor and cause serious damage. For fresh water applications, exhaust parts might last much longer, but routine maintenance is still necessary. If you have a 4.3L MerCruiser engine, you’ll need 4.3 exhaust kits or individual components from our large inventory. NuWave Marine is proud to carry only premium OEM parts and high-quality Sierra aftermarket parts. Stop a small problem from becoming a big one with these exhaust system replacement parts.
MerCruiser 4.3 Exhaust Manifold
Venting hot gasses from the cylinders is an important job and it all starts with your manifold. Exhaust manifolds from NuWave Marine are precision-engineered to be efficient, durable, and easy to install. Made to handle the outflow of gasses from these powerful engines, a new manifold is a must if you notice any sort of corrosion or leakage.
MerCruiser 4.3 Exhaust Y Pipe
In addition to riser elbows, MerCruiser 4.3 Y pipes play an important role in venting gas collected by the manifold outward. Y pipes take exhaust from two separate manifolds and combine it into one transom assembly. Just like with the manifolds, if you notice any seepage, leakage, or corrosion, the best course of action is to replace the part entirely.
We also carry other essentials for 4.3 liter MerCruiser motors. MerCruiser 4.3 spacer kits contain the parts you need to make sure your exhaust system sits at the right height. We also offer riser elbows, and smaller spare MerCruiser 4.3 exhaust parts like gaskets and bolts. If you need an entire new system, or just a new gasket, we’ve got all the MerCruiser exhaust replacement parts you require.
NuWave Marine has been fixing, building, and maintaining marine engines since 1987. If you have a question, drop us a line and let our experience work for you.
