Outboard Motor Lower Unit Assy
The gearbox is located below the outboard motor head, responsible for transferring power to the propeller and providing a deceleration ratio, because the speed of the internal combustion engine is too high and the torque is not suitable for ship propulsion, so the gearbox is needed to reduce the speed and lift torque, lower unit assy is mainly composed of transmission propeller shaft, outboard gear, and shell.
- Product Introduction
The gearbox is located below the outboard motor head, responsible for transferring power to the propeller and providing a deceleration ratio, because the speed of the internal combustion engine is too high and the torque is not suitable for ship propulsion, so the gearbox is needed to reduce the speed and lift torque, lower unit assy is mainly composed of transmission propeller shaft, outboard gear, and shell. Its main performance indexes are transmission efficiency, water resistance coefficient, and reliability and durability.
The lower unit assy for outboard motor is mainly used for underwater operation; during the production of the gearcase assy, we use oil for lubrication, cleaning and cooling of this pure mechanical gearcase box; outside the lower unit assembly, it will be painted to prevent rust.we have lower unit assy, casing lower, drive shaflt comp, propeller, propeller bushing, propeller shaft, propeller spacker kit, all accessories quality, complete range; When you need yamaha outboard motor accessories, please contact us.
