🔌 Function

The prop shaft oil seal seals around the propeller shaft at the bearing carrier. It keeps gear lubricant inside the gearcase and prevents water from entering the drive through the prop shaft seal area.

Common signs of failure:

• Milky or contaminated gear oil

• Gear oil leaking behind the propeller

• Failed lower-unit pressure or vacuum test

• Fishing line damage around the prop shaft

• Corrosion or seal wear around bearing carrier area

• Replacement required during prop shaft, bearing carrier or gearcase service

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
