Technodrive TM345 2.47:1 Marine Gearbox

Description

Match a vertical-offset output arrangement with the Technodrive TM345 2.47:1 Marine Gearbox. This marine gearbox is specified for displacement hulls and sailboats, with a 2.47:1 reduction ratio and a parallel output configuration with vertical offset.

Model TM345-247 uses a hydraulic multi-disc clutch and has a maximum pleasure-use input rating of 110 HP (82 kW) at 3,000 RPM. Its separate continuous-duty input rating is 55 HP (41 kW) at 3,000 RPM. Service data lists SAE 20W40 or SAE 15W40 oil, a 0.42-gallon (1.6-liter) capacity, and a dry weight of 51 lb (23 kg).

Fitment and Propulsion Use

The Technodrive TM345-247 is specified for displacement hulls and sailboats. It supports propulsion systems requiring a 2.47:1 reduction ratio and a parallel output configuration with vertical offset. The listed pleasure-use and continuous-duty ratings are both based on 3,000 RPM, so verify the engine output, transmission interface, shaft geometry, and vessel-duty profile before ordering. 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 that the parallel vertical-offset output arrangement, 2.47:1 reduction ratio, engine input rating, and installation geometry match the vessel drivetrain. Use only the listed SAE 20W40 or SAE 15W40 oil and 0.42-gallon 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 Technodrive TM345

Verify that Technodrive model TM345-247 matches your displacement-hull or sailboat propulsion system. Confirm the 2.47:1 reduction ratio, parallel output with vertical offset, 110 HP (82 kW) maximum pleasure rating at 3,000 RPM, 55 HP (41 kW) maximum continuous rating at 3,000 RPM, hydraulic multi-disc clutch, SAE 20W40 or SAE 15W40 oil requirement, 0.42-gallon (1.6-liter) oil capacity, and 51 lb (23 kg) dry weight. Confirm compatibility with your engine manufacturer’s documentation before purchase.
