MerCruiser 4.3 Exhaust Riser Spacer Kits

MerCruiser 4.3 Exhaust Riser Spacer Kits

MerCruiser 4.3 exhaust riser spacer kits from PowerBoatSupply.com 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 PowerBoatSupply.com, 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.
