Hydraulic gearbox Technodrive TM-345A for marine engine

Saildrive and gearboxes

The TM345A marine transmission has an aluminium alloy housing and is equipped with hydraulically activated multiple disk clutches. The clutches and gears have been designed to transmit full power, with the same transmission ratio in forward and reverse. The 8º angle of depression of the output shaft makes it possible to correctly install the marine engine-transmission set on planning or semi-displacement hulls.
