Important Facts


Are your Risers too short?

A poorly engineered cooling system might create the unfortunate situation of causing seawater to backfill into the engine. To prevent this, consider raising the height of the risers to create a new high point that the seawater cannot pass.   


Getting water in your Engine.

A marine cooling system acts like a double walled pipe inside another pipe. The independent cavities keep the exhaust gas away from the cooling water. A breach between the two cavities can cause cooling water to enter the cylinders. This can rust the cylinders, contaminate the engine, crack pieces and cause costly damage. Proper and timely replacement of cooling components can prevent this damage.


Why Custom? Why Ours?

Some boats can use standard replacement part numbers right from a catalog but many boats require custom components that we can fabricate. One reason for customizing is to replace rare, out of production pieces. Another reason is to change the specifications such as raising the height of the riser to prevent seawater from back flowing in to the engine. Another reason for using our services is to repair components. This might save money over replacement. Call us to find out the best option for you.
