Fitment and Propulsion Use

The Advance HCT800-568 is specified for coastal freighters and marine repower projects. It supports propulsion systems requiring a 5.68:1 reduction ratio, subject to matching the engine’s rated torque, operating RPM, SAE 00 or SAE 0 bell housing interface, propeller-thrust requirement, and complete shaft 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

For a repower installation, verify the SAE 00 or SAE 0 bell housing interface and confirm that the vessel structure, engine alignment, and propeller-shaft geometry accommodate the 17.72-inch center distance, 41.6 x 50.4 x 56.1 inch housing, and 5,952 lb dry weight. The supplied data lists a 17.1-gallon oil capacity. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.

Before Ordering the Advance HCT800
