Detailed Product Description
Features of Marine gearbox series MA:
1. The hydraulic system built in the gearbox makes the operation easy from the bridge with remote control. A unit of pressure delay stepping up is fitted in the hydraulic control system and the cluth is smooth in engagement and thorough in disengagement.
2. Two sets of multiplate clutches are mounted at the output end and easy to dis- and re-assemble and mainenance.
3. The housing is integral to ensure its rigidity and the precision for engaging.
4. Both ahead and astern are identical in reduction ratios and can transmit the rated power, especially suitable for boats equipped with twin-engines, which have the same rotation, and twin-propellers.
5. The emergency set is provided to ensure the boat travelling continuously in case of severe hydraulic failure.
6. Bell housing and flexible input coupling are connected with the engine so as to be looked-perfectly the whole unit and easily in mounting.
7. The rage of the speed reduction ratios is wider as follows. Users can choose the ratio suitable to transmission capacity in accordance with the data of the engine or the boat.
