MerCruiser 2010+ EC Catalyst Exhaust
PowerBoatSupply.com has the MerCruiser Catalyst exhaust parts and kits you need to upgrade your exhaust system or replace worn-out or faulty components to keep your boat engine humming like new.
If you’ve ever worked with any type of internal combustion engine, you know the exhaust system plays a vital role. Whereas with a car, a poorly maintained exhaust can lead to poor engine performance, on a boat, the stakes are much higher. A leaky gasket or corroded part can lead to water seeping into your engine, which can have disastrous results. At PowerBoatSupply.com, we recommend that salt water engines have their exhaust systems inspected regularly, and replaced after 5 years. For fresh water applications, they can last longer, but it’s still important to keep a close eye on them, especially if they are older.
MerCruiser Catalyst Parts
When it does come time to replace the exhaust on your MerCruiser engine, PowerBoatSupply.com makes it easy to find MerCruiser parts. Upgrading to a MerCruiser Catalyst exhaust is highly recommended, since this high-tech exhaust system helps reduce emissions. A new MerCruiser Catalyst system will efficiently vent gasses from your engine and reduce pollution. They are good for your boat and good for the planet. Emissions requirements vary state by state, and country by country, but what is good for the environment anywhere, is good for everyone.
