Adding your products to cart

MerCruiser 4.3 exhaust riser spacer kits from NuWave Marine will help you mount your exhaust riser at the proper height. To keep water from potentially backflowing into your marine engine, you need to make sure your riser elbow is at the appropriate height. Spacer kits, or blocks, are designed to add height, usually 3-6 inches, to the riser elbow. For boats where the engine sits lower in the water, this is an important necessity. At NuWave Marine, we recommend inspecting and replacing your riser blocks at regular intervals as part of routine MerCruiser exhaust maintenance. You should be inspecting your exhaust system once a year and paying careful attention to joints, gaskets, and any area that might be starting to rust. We recommend replacing saltwater parts every five years. Freshwater engine parts will probably have a longer lifespan, but it pays to keep a close eye on those, too.

MerCruiser Exhaust Riser Spacer Kits

Your MerCruiser 4.3 exhaust is a complex system, and it’s imperative that every part is manufactured to meet exact specifications. Every MerCruiser exhaust riser spacer from NuWave Marine is made from high-quality metal and built to fit perfectly with your manifold and riser elbow. In short, they're precision-engineered parts that you can count on.

MerCruiser 4.3 Spacer Block Kit

The spacer block kit from NuWave Marine contains all the parts you need to properly elevate your risers, including gaskets and bolts. They’ll elevate the key point where your risers meet the MerCruiser 4.3 exhaust Y-pipes and help keep water from sneaking into your motor. Should your spacer kit need a little TLC between overhauls, we also carry MerCruiser 4.3 gaskets and bolts to meet a large variety of specifications.
