Sierra Lower Unit Gear Housing Seal Kit for Johnson/Evinrude Outboards

The Sierra Lower Unit Gear Housing Seal Kit is designed for servicing the lower unit (gearcase) of Johnson and Evinrude outboard motors. Each kit in this product line is made to help restore a proper seal during a lower unit rebuild. This helps keep water out and gear lube in. Marine mechanics and DIY boat owners can use these seal kits for routine maintenance and gearcase overhauls.

Key Features:

• Made for Johnson/Evinrude outboard lower unit gear housing service
• Helps keep water out of the gearcase and lubricant in
• Helps protect gears and bearings from corrosion and premature wear
• Aftermarket replacement from Sierra, a long-established marine parts brand
