Convenient transmission shaft installation design

Outlet flange is at a downward 7°angle,convenient for installation and meeting the propeller requirements.

More flexible and convenient operation

There are three gears: forward, neutral, and reverse. Gear selection is fast and easy.

Cone type clutch shifting system

The cone face contacts incrementally until the torque transition is made smoothly.

Reliable and durable marine gear box

Corrosion resistant material, heat treatment, machining of different working surfaces and precision gear design fully ensure the reliability and durability of the gearbox.


The marine engine (with gearbox) is adapted from Kipor’s marine product design series. The oil consumption, noise and emissions are low and reliability is high. The gearbox series, KDMD11, KDMD21 and KDMD28: the inside gears mesh utilizing a cone clutch making for a more stable operation and avoiding friction wear.. The gears are made of high strength alloys for a long service life.

KDMD100 and KDMD300 gearboxes use a hydraulic shifting system which is quiet and free of vibrations. The gearbox is cooled with fresh and sea water ensuring effective and reliable operation. The output axis flange is inclined 7°and facilitates installation. There are 3 gears (forward, neutral and reverse).

The engine can be installed in virtually any hull location featuring inside axis propulsion while providing convenient installation and maintenance.
