75W-90 Synthetic Marine Gear Lube
True marine gear performance. Provides superior protection from shock loading. Resists foam and retains extreme-pressure qualities even when subjected to 10% water contamination. For use in outboard lower units, sterndrives, V-drives, bow and tunnel thrusters and marine transmissions Excellent for use in ATVs.
AMSOIL Synthetic Marine Gear Lube is an exclusive AMSOIL formulation of synthetic base oils and high-performance additives that addresses the specific concerns of marine applications. It is fortified with extreme-pressure (EP) additives for superior protection of fast-accelerating, high-torque/horsepower engines. It protects against shock loading from cavitation of heavily loaded engines.
AMSOIL Synthetic Marine Gear Lube is water resistant. It maintains extreme-pressure protection even when contaminated with as much as 10 percent water. It promotes longer seal life to help prevent water contamination. AMSOIL Synthetic Marine Gear Lube is designed to prevent rust and is compatible with aluminum, copper and brass alloys.
Marine gear oils operate in environments subject to water contamination. The chart above demonstrates the ability of AMSOIL Synthetic Marine Gear Lube to maintain designed qualities such as extreme-pressure/anti-wear performance and resistance to foaming, even when subjected to 10 percent water contamination.
The Falex Procedure is a measurement of a gear lube's extreme-pressure and anti-wear properties. A high value in the Falex Extreme-Pressure Test relates to extra extreme-pressure protection. AMSOIL Synthetic Marine Gear Lube provides extreme-pressure protection and is highly resistant to the effects of water contamination.
The presence of foam in a lubricant disrupts the oil film and promotes wear. Water contamination can increase the likelihood of foaming. Industry-standard testing demonstrates zero foam in both new and water-contaminated AMSOIL Synthetic Marine Gear Lube.
- Excellent gear and bearing protection, even when contaminated with 10% water
- Reduced friction and wear
- Protection against rust and corrosion
- Long seal life
- Superior foam prevention
Use in fresh- and saltwater applications that require 75W-90 or 80W-90 gear lube and any of the specifications listed below, including lower units made by Mercury/Mariner*, Johnson/Evinrude*, Bombardier*, Honda*, Yamaha*, Suzuki*, Force/US Marine*, Nissan*, Tohatsu* and Harbormaster*; sterndrives made by Mercruiser-Bravo*, OMC/Bombardier, Volvo-Penta*, Yanmar*, Konrad* and Marine Drive Systems*; V-drives made by Casale & Menkins*; bow thrusters made by Harbormaster Marine*; and transmissions made by ZF Marine Transmission*.
- API GL-4, GL-5
- Follow manufacturers' recommended service intervals.
- It is generally a good idea to change gear lube at the end of a season prior to storage.
