TM 345A

The MG-5005A/Technodrive 345A marine transmission features a durable aluminum alloy housing and hydraulically operated multi-disc clutches. The clutches and gears are engineered to handle full engine power in both forward and reverse, with an identical gear ratio in either direction. The transmission's output shaft is set at an 8 degree down angle, making it ideal for proper alignment in engine-gearbox setups on planning 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.
