Technodrive: Brand Overview <

TM 93 A

The Technodrive TM 93 A marine transmission is equipped with hydraulically operated multi-disc clutches. Both the clutches and gears are designed to transmit full engine power with the same gear ratio in both forward and reverse. An 8 degree down-angle on the output shaft ensures proper alignment for engine and gearbox installation in planing or semi-displacement hulls.

Torsional Responsibility

Disregarding propulsion system torsional compatibility could cause damage to components in the drive train resulting in loss of mobility. At minimum, system incompatibility 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 driven equipment.
