Adding your products to cart

Marine engines require parts and accessories tailored specifically to their needs. One essential example: gear lube. Whether you need a Premium or High-Performance formula, MerCruiser gear lube is rigorously tested for purity and fortified with the additives and emulsifiers that your boat's systems need to protect against metal-on-metal friction and the corrosion marine engines are susceptible to.

MerCruiser Premium Gear Lube

MerCruiser's premium-grade gear lube works hard to help extend gear life and keep your engine running at peak performance by:

  • Preventing pitting and corrosion.
  • Preventing mechanical failure due to flooded gear housing. 
  • Offering maximum protection against the wear and tear your components endure - both in the water and out.

This premium gear lube is recommended to enhance overall performance of lower units for outboards below 75 horsepower. Double-check to be sure you have the right lube and MerCruiser gear lube reservoir to outfit your system!

MerCruiser High-Performance Gear Lube

MerCruiser's high-performance gear lube does all the same things as the premium grade, but it's specially formulated to optimally work with high-speed/high-horsepower/high-performance systems. (Looking for the ideal MerCruiser Bravo 3 gear lube? This is it.)

MerCruiser High-Performance Gear Lube will deliver: 

  • Additives formulated to prevent metal-on-metal mayhem in internal components. 
  • Emulsifiers that go the extra mile to protect internal components from rust and corrosion in the event your lower gear case is flooded. 
  • A gear lube formula exclusively designed to protect in challenging conditions like high-horsepower/high-speed applications. 

Note: Mercury Premium SAE 80W90 Gear Lube and Mercury High-Performance SAE 90 Gear Lube should not be mixed!

Good to Know: Marine gear lube isn't officially protected by industry-wide quality measures. That’s why it’s vital to use the highest quality products specifically tested and designed for marine applications.

Regardless of what job you need to tackle, you're covered with our wide selection of MerCruiser drive parts, MerCruiser maintenance gear, and more.
