Hydraulic gearbox Dong-i DMT-100IV for marine engine
Saildrive and gearboxes
The Dong-i DMT100IV marine transmission, constructed from highly stiff and seaworthy aluminium, is engineered for lightness and marine efficiency. It features a remote control via a shifting valve (both mechanical and electrical) and boosts engine efficiency with a 14° conical gear. The design allows for easy maintenance of the gearbox by adjusting the engine installation space. Developed under the ISO9001 quality system and adhering to DNV and ISO6336 standards, this transmission is suited for high-speed propulsion systems using both surface drive and propeller shaft types. Its efficient design ensures optimal space utilization on vessels.
