SEAL KIT 26-89238A2

Function and technical context

This seal kit guarantees tightness in the propulsion systems of high-performance Mercury engines, preventing water infiltration and loss of lubricant in critical areas of the propeller. The seals work in the lubrication and cooling circuit of the engine, supporting dynamic pressures and temperature variations typical of marine navigation. Its deterioration causes internal leaks, salt water entry into the crankcase, accelerated corrosion of internal components and progressive loss of power, compromising the safety and reliability of the boat.

When to replace this part?

The seals show visible wear when you detect oil leaks around the transmission shaft, changes in the color of the cooling fluid or the presence of moisture in the crankcase after sailing in salt water. It is recommended to inspect this kit during each seasonal maintenance and replace it preventively every 5-7 years or after 1,000 hours of operation, especially if the engine has worked in salt or cloudy water conditions. Preventatively changing seals prevents costly repairs to the entire engine and ensures the airtight seal necessary for safe boating.
