AMSOIL Synthetic Marine Gear Lube is an
exclusive AMSOIL formulation of synthetic base oils and high-performance additives that address 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% water. It promotes longer seal life to help prevent water contaimantion. AMSOIL
Synthetic Marine Gear Lube is designed to prevent rust and is compatible with aluminum, copper and brass
AMSOIL Synthetic Marine Gear Lube is recommended for
fresh and salt water applications requiring either 75W-90 or 80W-90 viscosity grade and meeting either API
GL-4 or GL-5 performance standards.
Examples of AMSOIL Universal Synthetic Marine Gear Lube applications include:
Outboard lower units: Mercury/Mariner, Johnson/Evinrude, Bombardier, Honda, Yamaha, Suzuki,
Force/US Marine, Nissan, Tohatsu, Harbormaster Marine Outboard Drives, Sears Gamefisher and Seagull.
Sterndrives: Mercruiser-Bravo, OMC/Bombardier, Volvo-Penta, Yanmar, Konrad
Marine Drive Systems.
Bow & Tunnel Thrusters: Harbormaster Marine
Marine Transmissions: ZF Marine Transmission
AMSOIL Synthetic Marine Gear Lube provides:
- Excellent gear and bearing protection even when contaminated with 10%
- waterReduced friction and wear
- Rust and corrosion protection
- Long seal life
- Superior foam prevention
Marine gear oils operate in environments subject to water contamination. The chart demonstrates the ability of
AMSOIL Synthetic Marine Gear Lube to maintain designed qualities such as extreme-pressure/anti-wear performance and
resis-tance 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 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.
AMSOIL Synthetic Marine Gear Lube is compatible with other commercially available conventional and synthetic
marine gear lubes.
Follow manufacturers' recommended service intervals.
It is generally a good idea to change gear lube at the end of a season prior to storage.
