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 protects against 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:
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
Marine gear oils operate in environments subject to water contamination.
The chart below 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 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 water-contaminated AMSOIL Universal
Synthetic Marine Gear Lube. Other conventional gear lubes can
foam when mixed with water, as seen in the graph.
