YAMAHA PROPELLER 7-1/2X7 6E0-45943-01-EL PAF4-03070000

Function and technical context

The propeller is the fundamental propulsion element that transforms the engine's power into direct thrust on the water. In Yamaha outboard engines, the propeller works coupled to the drive shaft, transferring the rotation of the crankshaft to the submerged impeller. Its 7.5-inch diameter, 7-inch pitch design is optimized for small and medium-sized boat applications, ensuring a balance between speed and traction. Wear or loss of material in the blades significantly reduces propulsive efficiency, causing loss of speed, excessive fuel consumption and hull vibration.

When to replace this part?

A propeller requires visual inspection at each seasonal maintenance, especially if sailing in waters with vegetation, remains of nets or rocky bottoms. The most obvious symptoms of wear are the loss of revolutions at full throttle, unusual vibrations in the tiller, or the detection of cracks and fissures in the blades. It is recommended to keep a spare propeller on board, as preventative replacement prevents unexpected being left in the water and prolongs the life of the power train.
