      MerCruiser Cooling Systems

      The cooling system of your MerCruiser engine keeps it from overheating and ensures that it’s operating at its best. It’s important to keep the entire cooling system updated and maintained, since its health is at the forefront of your engine’s overall performance. If you need parts for your MerCruiser cooling system, simply call Wholesale Marine. We will always have just what you need.

      Keep it Cool with MerCruiser Cooling Systems

      A boat’s engine, such as your MerCruiser sterndrive or inboard engine, is a delicate piece of machinery full of moving parts that each need special attention. In times past, a boat's engine was simply cooled by pulling raw water straight out of the source the vessel was floating in, running that through the engine, and out the other end. This left an engine with several issues, such as saltwater corrosion, large debris, and lack of efficiency. Further still, this sort of cooling system once upon a time only ran at 145 to 150 degrees, as regulated by a thermostat, to avoid saltwater crystallization. This is an issue due to a number of reasons, one of which was the amount of build-up that would occur at such cool temperatures.

      Today, we have engines full of checks and balances to get our MerCruiser sterndrive or inboard at max power without overheating. And Wholesale Marine has everything you need to run preventative maintenance on your vessel and to upgrade your older parts. Water pumps, impellers, thermostats, gaskets, circulation pumps, shutter and exhaust tubes, exhaust manifolds, hoses, belts, and more are all here to fit MerCruiser cooling systems.
