Gearcase Seal Kit for 135-220HP Lower Unit 26-89238A2 18-2655 This gearcase seal kit is designed for use with outboard engines in the 135-220HP range.It corresponds to part numbers 26-89238A2 and 18-2655.The kit contains seals and gaskets intended to seal the lower unit of the outboard engine, which houses the gearcase responsible for transferring power from the engine to the propeller.Over time, exposure to water, salt, and mechanical stress can cause these components to wear, potentially allowing water entry into the gearcase. The contents of this kit typically include a main seal to prevent water entry into the gearcase, a shaft seal located around the propeller shaft, gaskets for sealing components such as the gearcase cover, and O-rings for creating seals between moving and stationary parts.These components are manufactured to fit engines compatible with the specified part numbers and horsepower ratings. Replacement of these seals is indicated by signs such as water presence inside the gearcase, oil leaks from the lower unit, difficulty shifting gears, or unusual noises during.Installation requires standard tools including a gearcase cover removal tool, seal driver, and torque wrench.Users should refer to the manufacturer's manual for specific installation instructions and torque specifications.Applying sealant to gasket surfaces and inspecting the lower unit for damage prior to installation are recommended steps.After installation, the engine should be tested to verify proper function and check for leaks.This kit serves as a replacement solution to restore the sealing function of the lower unit.
