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.
