High Performance Lubricant Engineered to Meet the Demands of Marine Applications.
AMSOIL Universal 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
extreme pressure (EP) additive fortified for
superior protection of fast accelerating, high torque/horsepower engines. It protects against shock loading from cavitation of heavily loaded engines.
AMSOIL Universal 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, preventing excessive water leakage.
AMSOIL Universal Synthetic Marine Gear Lube prevents rust and is compatible with aluminum, copper and brass alloys.
Applications
AMSOIL Universal 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. V-Drives: Casale & Menkens. Bow & tunnel thrusters: Harbormaster Marine. Marine Transmissions: ZF Marine Transmission
AMSOIL Universal Synthetic Marine Gear Lube provides:
• Excellent Gear and Bearing Protection even when contaminated with 10% water
• Reduced 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 Universal Synthetic Marine Gear Lube to maintain designed qualities such as extreme pressure/anti-wear performance and resistance to foaming, even when subjected to 10% 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 Universal Synthetic Marine Gear Lube is not affected by water and provides
50% more extreme pressure protection for long gear and bearing life.
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 watercontaminated
AMSOIL Universal Synthetic Marine Gear Lube. Other conventional gear lubes can foam when mixed with water, as seen in the graph.
AMSOIL Universal 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.
