Fitment and Propulsion Use

The Advance ADV300-204 is specified for high-speed ferries and service vessels. It supports propulsion systems requiring a 2.04:1 reduction ratio, subject to verification of engine rated torque, actual operating RPM, SAE bell housing interface, propeller-thrust requirement, and complete drivetrain arrangement. Confirm fitment using the engine model, serial number, rated torque, operating RPM, reduction ratio, and manufacturer drivetrain documentation before ordering.

Installation and Service Considerations

Verify the correct SAE 0 or SAE 1 bell housing interface and confirm that engine alignment, vessel mounting structure, shaft geometry, and available installation clearance match the transmission. Account for the listed 31.5 x 28.5 x 38.0 inch dimensions, 1,433 lb dry weight, and 10.63-inch center distance. The transmission has a listed oil capacity of 4.22 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
