Fitment and Propulsion Use

The Advance D300A-590 is specified for coastal freighters and trawlers. It supports propulsion installations that require a 5.90:1 reduction ratio, subject to verification of engine rated torque, operating RPM, maximum input rating, SAE 0 or SAE 00 interface, propeller-thrust requirement, and actual shaft configuration. 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 that the engine-to-transmission connection uses the correct SAE 0 or SAE 00 bell housing standard and confirm the complete alignment, shaft geometry, 13.78-inch center distance, and structural space required for the 36.0 x 32.5 x 45.0 inch housing. The transmission has a listed oil capacity of 5.28 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
