Gear Cases

An outboard Engine’s gear case transmits the engines power to the propeller. It also drives the liquid cooling system of the engine an impeller connected to the drive shaft.

They are single ratio with forward and reverse gear.
Prop size will vary with engine power and suitability to specific role.

Lubricants used in marine gear oils need to be generally API GL5 and work over a wide heat range. They should also contain anti rusting agents
