PowerBoatSupply.com carries all the MerCruiser 5.0, 5.7, and 6.2 exhaust parts you need to completely redo your boat’s exhaust, top to bottom. When it comes to your exhaust system, the little things can make a big difference - or cause a big problem. As part of your seasonal inspection, if you notice any wear, tear, or corrosion on your MerCruiser 5.0 gasket set, you should replace it immediately. This goes for 5.7L and 6.2L engines as well.
MerCruiser 5.0 Intake Manifold Gasket
Keeping water out of your engine is really about two things: First off, make sure your riser elbow is at the correct height to prevent backflow. Second, but no less important, come the seals between your engine and manifold, manifold and riser, and the riser and the rest of your exhaust. Though you may not notice water seeping in from the outside, a damaged MerCruiser 5.7 exhaust gasket, for example, can be leaking small amounts of cooling water into your engine. Even a small imperfection in this seal can have catastrophic consequences. Make sure you have the right MerCruiser spacer kits to connect your exhaust system parts, and make sure your MerCruiser 5.7 exhaust manifold gasket is in good condition.
MerCruiser 5.7 Exhaust Riser Gasket
For saltwater applications, it’s recommended that you inspect your exhaust every year, and replace your exhaust system every 5 years completely. Certain parts might last longer, but you’re really tempting fate by putting off this routine maintenance. Freshwater engines should need less monitoring, but it’s still important to keep a keen eye on all the little parts, like gaskets and bolts. If you need small replacement parts, bolts and gaskets from this collection will do just fine. However, if it’s time to replace your whole exhaust system, consider buying full exhaust kits from PowerBoatSupply.com.
