MerCruiser 4.3 Gaskets and Bolts

MerCruiser 4.3 Gaskets and Bolts

NuWave Marine carries the MerCruiser 4.3 gaskets and bolts you need to properly maintain your boat's engines. We recommend inspecting these parts yearly and replacing the entire exhaust system every 5 years for saltwater applications. Whether you're a veteran mechanic or servicing a motor for the first time, you know that a MerCruiser exhaust has a lot of moving parts. It’s very important to pay attention to the big parts like exhaust manifolds and risers, but don’t overlook smaller components. It’s imperative that your gaskets and bolts are in good shape if you want to prevent water from leaking into the engine. Replacing a simple gasket before it fails can be the difference between keeping your engine running perfectly, and major water leakage.

MerCruiser 4.3 Gasket Set

The MerCruiser 4.3 gasket set from NuWave Marine has all the parts you need to replace the gaskets on your MerCruiser 4.3 exhaust. If you're redoing all your gaskets, it makes sense to buy the full set. If you're just looking for a single gasket, we carry those, too. Keep in mind that when one gasket is starting to wear out, the others probably aren’t far behind. Given that gaskets are relatively inexpensive, it’s usually a good idea to replace them all at once when you start to notice any signs of degradation.

MerCruiser 4.3 Riser Gasket and Bolts

MerCruiser 4.3 manifold bolts and riser gaskets are essential parts that will keep cooling seawater or lake water out of your engine. Of course, they do handle a lot of stress due to the demands of a powerful 4.3L engine and the unique demands of a marine environment. As you’re checking gaskets, remember to also closely inspect your bolts.
