DIABOLO 93315-43061

Function and technical context

The diabolo is a critical component of the transmission system in outboard motors, responsible for transmitting power from the crankshaft to the propeller through connection with the output shaft. It works within the propulsion system's gear and pinion group, supporting significant torque loads during acceleration and cruising at different speeds. A worn or damaged diabolo causes loss of traction, abnormal vibrations in the shaft, difficulty changing gears and, in severe cases, inability to transmit power to the propeller.

When to replace this part?

Signs of wear on the diabolo include difficulty engaging gears, noticeable vibrations in the rudder during acceleration, metallic noises coming from the gear group, and noticeable reduction in traction capacity. It is recommended to check the condition of this component during each seasonal maintenance, especially after intensive navigation in salt water or in shallow conditions. Preventive replacement of the diabolo prevents secondary damage to the gearbox and other components of the propulsion system.
