Fitment and Propulsion Use

The Advance D300A-706 is specified for deep-sea trawlers and heavy tugboats. It supports a propulsion configuration requiring a 7.06:1 reduction ratio, subject to confirmation of the engine’s actual rated torque, 2,400 RPM maximum input speed, SAE interface, propeller-thrust requirement, and full 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 SAE 0 or SAE 00 bell housing interface and confirm installation space for the 36.0 x 32.5 x 45.0 inch gearbox and its 1,940 lb dry weight. Check the engine-to-gearbox alignment, shaft geometry, 13.78-inch center distance, and service access before installation. The listed oil capacity is 5.28 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
