Marine Gears
Definition
Twin Disc model MG5114SC The engaged position is the normal operating position and water will discharge from the water jet steering nozzle. The
disengaged position disconnects the water jet from the engine and there is no discharge. The backflush position reverses the rotation of the pump impeller and water will discharge from the water jet intake.
Term
Reduction Ratio and Control Valves
Definition
The reduction ratio is 1.02:1 in forward and reverse. Electronically-actuated control valves are mounted on the marine gear. The clutch control panel sends signals to these valves to control gear function.
Term
Gear lubricating oil
Definition
The gear uses approximately 2.8 gallons of 15W40 lubricating oil for clutch
pressure and lubrication.
Term
Marine Gear is cooled by
Definition
Raw Water from Engine Raw water system

Term
Raw water
Definition
The primary raw water system removes heat from engine coolant, engine fuel, engine
combustion air, and marine gear oil to maintain proper operating temperatures and provides cooling and quieting for engine exhaust.
Term
