Product Details

The Quicksilver 8M0236271 is a 1.75-liter (59.2 oz) bottle of Quicksilver High Performance Gear Case & Trim Fluid, engineered by Mercury Marine for demanding marine sterndrive and outboard lower unit applications. This premium SAE 90 semi-synthetic blend is purpose-built to outperform conventional automotive gear oils in the corrosive, water-rich marine environment.

Key Features:

  • Marine-Specific Formula: Specially engineered for outboard and sterndrive gearcases operating in both freshwater and saltwater environments
  • Advanced Additive Package: Tackifiers and extreme-pressure additives improve oil film adhesion to gears and internal components, guarding against metal-on-metal contact and excessive wear
  • Water Intrusion Protection: Advanced emulsifiers protect gears and internal components if water enters the gear housing or lower unit
  • Corrosion & Pitting Resistance: Inhibitors prevent rust, corrosion, and pitting to extend gearcase component life
  • High-Temperature Stability: Formulated to resist viscosity breakdown and help prevent horsepower loss when gears reach elevated operating temperatures
  • Generous 1.75L Size: Larger-format bottle ideal for multiple services or higher-capacity sterndrive gearcases
  • OEM Approved: Developed and tested by Mercury Marine to OEM specifications; maintains warranty coverage for MerCruiser sterndrives and Mercury, Mariner, and Force outboards

Service Interval: Quicksilver recommends changing gear lube at least once per season (prior to winterization storage) or every 100 hours of operation, whichever comes first. Always consult your engine owner's manual for model-specific recommendations.

Quicksilver is the premier marine lubricant brand from Mercury Marine, with over 65 years of experience formulating oils and fluids specifically for the rigors of marine use. The 8M0236271 is the OEM part number for this product.
