Fitment and Propulsion Use

The Advance ADV300-544 is specified for industrial barges and coastal freighters. It supports propulsion systems that require a 5.44:1 reduction ratio and must be matched to the engine’s actual rated torque, maximum operating RPM, SAE 0 or SAE 1 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

Verify the required SAE 0 or SAE 1 bell housing interface, then confirm engine alignment, propeller-shaft geometry, mounting structure, and clearance for the 31.5 x 28.5 x 38.0 inch transmission and 1,433 lb dry weight. the listed oil capacity is 4.22 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
