Fitment and Propulsion Use

The Advance HCT600A-866 is specified for heavy-displacement trawlers and tugs. It supports drivetrain arrangements requiring an 8.66:1 reduction ratio, with engine input limited to the listed 756 HP at 2,100 RPM rating and 2,100 RPM maximum input speed. 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 correct SAE 00 or SAE 0 bell housing connection and verify engine-to-gearbox alignment, shaft geometry, propeller-thrust requirements, and available structural space before installation. Allow for the 31.7 x 43.1 x 50.0 inch housing, 3,527 lb dry weight, and 16.34-inch center distance. The listed oil capacity is 10.6 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
