YAMAHA GASKET 6AW-11351-00

Function and technical context

This gasket is part of the critical sealing systems in high-power Yamaha engines, guaranteeing tightness at joint points where the passage of fluids and the entry of cooling water is prevented. Its main function is to maintain the structural integrity between engine components, avoiding leaks that would compromise the performance and durability of the propulsion unit. Failure or deterioration of this gasket can cause loss of coolant, entry of seawater into areas where it should not be present, and consequently overheating of the engine or accelerated internal corrosion.

When to replace this part?

Engine gaskets require replacement when visible leaks, rust around sealing joints are detected, or during preventative maintenance after disassembling engine components for repairs or service. In frequent navigation or in salt waters, it is recommended to inspect the condition of these seals at each seasonal inspection, especially before starting the summer campaign. Replacing these parts preventively during scheduled repairs prevents small leaks from developing into costly damage to internal engine systems.
