Gearbox (Medium)
A critical component used in
marine propulsion systems to
transfer power from the engine
to the propeller shaft, these
gearboxes are designed to handle
the torque and power generated
by marine engines, while also
optimizing the rotation speed
to suit the needs of the vessel’s
propulsion system, typically,
medium-sized marine gearboxes
are used for engines ranging from
500 to 3,000 horsepower (HP).

Gearbox (Small)
A vital component in marine propulsion systems,
typically used in smaller vessels, its primary function
is to transmit power from the engine to the propeller
while reducing the engine’s high RPM (revolutions per
minute) to a more suitable speed for the propeller.
