YAMAHA ENGINE COOLING GASKET 6E5-41112-A1

Function and technical context

This gasket forms an integral part of the Yamaha engine cooling circuit, sealing the joints between ducts and components of the cooling system. Its mission is to guarantee the absolute tightness of the circuit to prevent cooling water leaks that would compromise the integrity of the cylinders and engine liners. Progressive wear due to aging or thermal fatigue generates coolant losses, severe reduction in cooling efficiency and critical risk of overheating during loaded navigation.

When to replace this part?

It is advisable to examine the condition of the cooling joints at each seasonal inspection, especially if coolant stains appear around the connections or abnormal drops in the tank level. Although there is no universal replacement interval, preventive renewal is recommended every 3 to 5 years or after 500-800 hours of operation, depending on use and operating conditions. Changing it preventively before it fails completely prevents sudden breakdowns in navigation and costly engine repairs.
