STARBOARD WATER INTAKE GRID 61A-45215-10

Function and technical context

The water intake grille is an essential component of the salt water circulation cooling system in marine engines. This piece acts as a protective filter at the entrance to the cooling circuit, preventing remains of algae, sand, shells and other sediments from seawater from clogging the internal galleries of the engine. It works under conditions of variable pressure depending on navigation speed and depth, being critical to maintain a constant flow of cooling water to the engine block. A blockage or deterioration of the grille causes engine overheating, reduced power and, in extreme cases, irreversible damage to the cooling system.

When to replace this part?

The water intake grate must be checked at the beginning of each navigation season and after operations in turbid waters or with a high concentration of sediments. Symptoms of clogging include excessive engine temperature rise, fluctuations in the cooling thermometer reading, or a noticeable reduction in flow in the hot water discharge pipe. It is recommended to inspect the grate every 50-100 hours of navigation and replace it if it shows corrosion, deformation or adhered deposits that are not removed by cleaning. Preventive replacement is a minimal investment that avoids catastrophic failures in high-altitude navigation.
