🔌 Function

  

The O-ring seals the housing joint against gear lubricant loss and water intrusion.

  

Common signs of seal failure:

  

• Gear oil leaks from the housing joint

• Water enters the upper gearcase

• Gear lubricant becomes milky

• O-ring is flattened or brittle

• Housing surfaces are corroded

• Internal bearings become noisy

• Pressure or vacuum test fails

  

Installation considerations:

  

• Clean the O-ring groove

• Inspect the housing for corrosion

• Use the specified O-ring lubricant

• Do not stretch or twist the O-ring

• Confirm the O-ring remains seated during assembly

• Tighten the housing evenly

• Pressure- and vacuum-test the drive

• Replace contaminated lubricant

  

📦 Condition

  

• Genuine OMC OEM part

• Brand new

• Supplied in genuine or equivalent protective packaging
