Fitment and Propulsion Use

The Advance HC400-338 is specified for commercial fishing vessels and medium tugboats. It supports propulsion systems requiring a 3.38:1 reduction ratio, subject to verification of engine rated torque, actual operating RPM, SAE bell housing interface, propeller-thrust requirement, and complete 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

Confirm the required SAE 0 or SAE 1 bell housing interface and verify that engine alignment, vessel mounting structure, shaft geometry, and propeller-thrust requirements match the installed transmission. Check available clearance for the 33.2 x 37.4 x 35.0 inch housing and 1,807 lb dry weight. The transmission has a listed oil capacity of 6.07 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
