Fitment and Propulsion Use
The Advance HC400-342 is specified for marine propulsion and repower projects. It supports a drivetrain layout requiring a 3.42:1 reduction ratio, with engine input limited to the listed 810 HP at 1,800 RPM rating and 1,800 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
For a repower installation, verify the required SAE 0 or SAE 1 bell housing connection, engine alignment, shaft geometry, mounting structure, and propeller-thrust requirement before installation. Plan for the 25.2 x 39.8 x 35.0 inch housing, 1,807 lb dry weight, and 10.39-inch center distance. The listed oil capacity is 6.07 gallons. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
