MerCruiser Exhaust Flappers
If you need to replace your MerCruiser exhaust flapper, NuWave Marine has got you covered with OEM parts, as well as aftermarket parts from trusted companies like Sierra and SEACHOICE.
A big part of keeping your boat’s engine running optimally is preventing water from sneaking into it. Exhaust flappers attach to the exhaust of a boat, and are designed to open when exhaust gasses are being vented, and close when they are not. Your MerCruiser exhaust system will need to be monitored at regular intervals to check for wear, and it’s always a good idea to take a look at your exhaust flappers, too. They can be damaged by prolonged exposure to hot exhaust, or just from extended use.
MerCruiser Exhaust Flapper
Whether your boat has a new MerCruiser 2100+ EC exhaust or an older design, you’ll need replacement flappers that are designed to fit. From small 3” flappers to larger 5-6” sizes, the experts at NuWave Marine can help you figure out which design works for your exhaust system. Of course, replacing the whole exhaust system might be the best choice, especially if it’s been several seasons since it was last serviced. Check out NuWave Marine’s MerCruiser OEM exhaust kits and find the set that’s right for you.
