Open Cooling Systems Often Break Down Needing Regular Maintenance.
Most engines in service today have an inlet for water to circulate and cool your engine's components. Constantly improving and maximizing the marine engine over the years has led to improvements for the cooling system. Open cooling systems are simple inexpensive and easy to maintain. Components that are exposed to the lake and sea water need to be replaced every couple of seasons. A closed cooling system is used for applications that will be exposed to saltwater, the rust-preventing antifreeze mix circulates through the engine block, and many components. As long as the mix is flushed every season, there is not a need to change pumps or thermostats unless needed or overhauling the engine.
