It is crucial to keep the temperature of your marine engine under control. Constant shifting between just hot and boiling will cause the engine to disintegrate pretty fast. A good engine cooling system will help to avert many problems. If you have no experience with marine cooling systems, do a little research and ask expert advice before you make a final decision.

Different Ways to Keep Cool

A keel cooling system is one of the various systems used to cool a boat engine. It's not recommended for high speed boats or very large ones. This cooling system consists of an expansion tank, a thermostat and housing, an exhaust and a cooling pump. It is sheer simplicity itself to install. The only drawback is that it is only adequate for cruising in shallow water.

For those looking for a less expensive cooling system, a raw water cooling system would be a good solution. This system is cheaper because it only needs one pump. These systems use the water directly from the sea, which is pumped in to cool the engine and then pumped right back out again. This system will almost certainly cost you more in the long run because it damages the engine in a very short time as it causes it to rust.

Another critical component of marine engine cooling systems is an expansion tank. This simply provides room when the coolant of the engine expands as a result of the heat. A heat exchanger is another necessary component. It transfers the heat from the engine coolant to the raw water.
