Sierra Lower Unit Seal Kit for Johnson Evinrude Outboard Motors Drive & Gearcase Parts

Sierra Lower Unit Seal Kits are replacement gearcase seal kits for Johnson and Evinrude (OMC) outboard motors. Use them when you reseal or rebuild the lower unit, also called the gearcase or drive. They replace the worn oil seals, gaskets and O-rings that keep gear lube in and water out.

Key Features:

• Made for Johnson/Evinrude outboard lower units and gearcase service
• Sierra designs its replacement parts to meet OEM specifications
• Kits bundle the seals, gaskets, O-rings and drain/fill plug washers needed for a lower unit reseal, so you don't have to source each piece separately
• Interchange references to OEM, GLM and Mallory part numbers are listed for each kit
• Kit contents differ by part number, so each kit matches a specific lower unit application

Sierra supplies marine engine parts to OEM engine builders and boat builders. A fresh seal kit helps protect the gears and bearings from water intrusion and lubricant loss. Pick the kit with the part number that matches your outboard's lower unit.
