TM 345 marine transmission is built with aluminium alloy housing and equipped with multiple-disc clutches hydraulically operated. Clutches and gears are properly constructed to transmit the full power, with the same ratio, both in forward and reverse running. An optional 8° down angle on output shaft provides a proper engine-marine gearbox group installation on planing or semi-displacement type hulls.

The gearbox used also has a major influence on the propeller used so please consult the prop manufacturer before selecting the appropriate model

At minimum, system incompatability could result in gear clatter at low speeds.The responsibility for ensuring that the torsional compatibility of the propulsion system is satisfactory rests with the assembler of the drive and the driven equipment.
