*Large skewed propeller blades increase the blade ratio, and reduce the probabilities of cavitations, noise and vibration to the large extent; reasonable blade tip clearance improves the propulsion efficiency significantly.
*The bevel gears are designed and manufactured to Class ISO-4 in house, which could satisfy the requirements of different input speed; the arrangement of bearings with long service life and high precision ensure the gear meshing accuracy.
*Reliable material: blades and hub are produced with high strength Ni-Al bronze, and the drive shaft and gear are made of high quality alloy steel.
