Protect your marine lower unit from the damaging effects of water intrusion and ensure proper lubrication with the Sierra GEAR HOUSING SEAL KIT. This essential kit contains all the necessary high-quality seals and gaskets required to rebuild and maintain the integrity of your gear housing. By preventing water from entering the lower unit, you safeguard the gears and bearings from corrosion and premature wear, extending the life of your outboard or sterndrive.

• Key Features
• Complete Seal Replacement: Includes all critical seals and O-rings for a comprehensive gear housing overhaul.

The Sierra GEAR HOUSING SEAL KIT is a crucial component for routine maintenance and repair of marine lower units. Water contamination in the gear oil can quickly lead to milky, emulsified oil, which loses its lubricating properties. This can result in gear damage, bearing failure, and ultimately, very expensive repairs. This kit provides the peace of mind that comes from knowing your lower unit is properly sealed and protected against the harsh marine environment.
