VST GASKET YAMAHA 62P-14984-00 REC6P2-14984-00

Function and technical context

This gasket seals the connection between critical components of the cooling and lubrication system on high displacement Yamaha outboard engines. It works under variable pressure and temperatures, avoiding leaks of coolant fluids and oil that would compromise the integrity of the engine. Its tightness is essential to maintain the pressure of the cooling circuit, prevent the entry of salt water into internal chambers and guarantee anti-corrosion protection of the engine block. A failure in this gasket can cause progressive loss of coolant, localized overheating and, during prolonged navigation, irreversible damage to the cylinder head or internal passages.

When to replace this part?

The joints in this area require visual inspection during each seasonal maintenance, especially after navigation in salt water, since the saline deposit accelerates the deterioration of the material. If you notice drips around the sealing area, color changes in the coolant, or slight smoke while boating, the gasket has lost its integrity. It is recommended to replace it preventively every two or three years of regular use, or after any intervention that has required disassembling components of the cooling system, to avoid emergency repairs that immobilize the boat in the water.
