WATER TUBE 61N-44362-00 PAF25-04000017S

Function and technical context

This tube is part of the outboard motor's cooling circuit, channeling the water flow to the internal cooling ducts. Its function is to maintain constant circulation of coolant from the external water intake system, ensuring that all cylinders and critical engine components receive homogeneous cooling. A degraded or clogged tube compromises the effectiveness of the cooling system, increasing the likelihood of engine overheating and subsequent catastrophic failure of gaskets, seals and internal components.

When to replace this part?

It is common for water tubes to suffer from porosity, microscopic cracks or hardening of the elastomer after several years of exposure to repeated thermal cycles and marine salinity. If visible losses are detected in the connections, color changes due to oxidation or excessive rigidity in the material, it is advisable to immediately replace them. Preventive replacement during seasonal inspection prevents small leaks from becoming costly breakdowns while boating.
