Specifications

Qualified marine gearbox with competitive price and best service.

Marine gearbox T300/1 possesses the functionis of ahead and astern, clutching and declutching, reducing speed and carrying the propeller thrust.

 

Marine gearbox T300/1 is designed with 5 shafts and 7 gears and two stage reduction, small in bulk, light in weight, smooth in engagement, reliable in opreation, easy in maintenance and durable in application.

 

The reduction ratios of marine gearbox T300/1 ranged from I=9: 1 to I=9.5: 1 and can be matched with medium and high-speed engines to increase the propulsive efficiency and tugging capacity.
