Product Details

The Quicksilver 43036 is a genuine OEM lower unit driveshaft oil seal designed for Mercury and Mariner outboard motors ranging from 40HP to 125HP. This critical seal prevents gear oil from escaping the lower unit gearcase while keeping water and contaminants out, protecting the internal gears and bearings from premature wear and damage.

Key Features:

  • Genuine Mercury Marine Quicksilver OEM part for reliable performance and precise fit
  • Measures 26.5mm x 37.4mm x 4.8mm (inner diameter x outer diameter x width)
  • Fits Mercury Mariner 2-stroke and 4-stroke outboards from 1988-2016
  • Compatible with 40-60HP, 75-90HP (3-cylinder), and 100-125HP (4-cylinder) models
  • Essential component for lower unit maintenance and gearcase seal replacement
  • Replaces Sierra 18-0522, Honda 91254-ZW1-003, and aftermarket equivalent 85170

This driveshaft seal is typically replaced during lower unit service, water pump replacement, or when gear oil leaks are detected. Regular inspection and replacement of lower unit seals during routine maintenance helps prevent costly gearcase damage and extends the service life of your Mercury outboard motor.
