Fitment and Propulsion Use
The Advance ADV300-300 is specified for tugboats and high-torque propulsion. It supports propulsion systems requiring a 3.00:1 reduction ratio, subject to matching the engine’s rated torque, operating RPM, SAE 0 or SAE 1 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
Verify the SAE 0 or SAE 1 bell housing interface and confirm that the vessel structure, engine alignment, and propeller-shaft geometry accommodate the 10.63-inch center distance, 31.5 x 28.5 x 38.0 inch housing, and 1,433 lb dry weight. the listed data lists a 4.22-gallon oil capacity. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.
