      Mercruiser Cooling System

      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, Wholesale Marine has all you need.

      We are Keeping it Cool!

      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 boats 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 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. Now we have engines full of checks and balances to get our Mercruiser sterndrive or inboard at max power without overheating. We have everything you need to run preventative maintenance on your vessel and to upgrade your older parts. Water pumps, impellers, thermostats, gaskets, circulation pumps, shutter & exhaust tubes, exhaust manifolds, hoses, belts, and more are all here to fit your Mercruiser cooling system. Ready to get started? Check out our easy-to-use Parts Selection tool to quickly get you exactly what you are searching for.

      For keeping that sterndrive, inboard, or tow sport engine cool come rain or shine, you can depend on Wholesale Marine to provide high quality parts from the top brands in the industry. Our same day shipping, free shipping on orders over $99, and price match guarantees give you quality parts in a timely and economical manner.
