Fitment and Propulsion Use

The Advance 120C-194 is specified for medium-speed commercial craft. It is intended for propulsion installations requiring a 1.94:1 reduction ratio and must be matched to the engine’s rated torque, operating RPM, bell housing interface, propeller-thrust requirement, and full drivetrain geometry. Confirm fitment using the engine model, serial number, rated torque, operating RPM, reduction ratio, and manufacturer drivetrain documentation before ordering.

Installation and Service Considerations

Confirm the required SAE 1, SAE 2, or SAE 3 bell housing and verify alignment between the engine, transmission, and propeller-shaft system. the listed data lists a 2.64-gallon oil capacity; follow the gearbox manufacturer’s documentation for the correct service lubricant and cooling arrangement. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
