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
