Fitment and Propulsion Use

The Volvo Penta MS25A 2.23 is specified for planing and semi-displacement hulls. It supports propulsion systems requiring a 2.23:1 reduction ratio and an 8-degree down-angle output configuration. Confirm the exact engine model, serial number, rated torque, operating RPM, shaft angle, shaft rotation, and installation interface before ordering.

Installation and Service Considerations

Verify that the 8-degree down-angle output configuration, 2.23:1 reduction ratio, 50 HP input rating at 3,000 RPM, and planned shaft geometry match the vessel drivetrain. Use only the listed VDS-3 or SAE 15W40 oil and 0.45-liter oil capacity as directed by the manufacturer’s documentation. Follow the engine and gearbox manufacturer’s installation manuals and product instructions for alignment, lubrication, controls, cooling connections, and service procedures.

Before Ordering the Volvo Penta MS25A

Verify that Volvo Penta model VP-MS25A-223 matches your planing or semi-displacement-hull propulsion system. Confirm the 2.23:1 reduction ratio, 8-degree down-angle output configuration, 50 HP (37 kW) maximum input rating at 3,000 RPM, mechanical cone clutch, Volvo Penta VDS-3 or SAE 15W40 oil requirement, 0.45-liter oil capacity, and 37 lb (17 kg) dry weight. Confirm compatibility with your engine manufacturer’s documentation before purchase.
