3-blade propellers | Choosing the right propeller
The fewer blades a propeller has, the more efficient it is. Unfortunately, fewer blades also means more vibration. Three-bladed propellers are the most common for pleasure boating because they offer the best compromise between smooth performance, speed and consumption. Propellers with 4 or 5 blades allow better acceleration and significantly reduce vibrations. On the other hand, it is to the detriment of maximum speed and fuel consumption. Each propeller blade has...

How to choose this product
3-blade-propeller

A three-bladed propeller is a metal device attached to the end of a boat engine's drive shaft. The shape of its blades converts rotation into thrust, propelling the boat forward.

Technologies

There are various sorts of three-bladed propellers, including outboard and inboard models intended for power vessels, as well as fixed or folding versions for sailboat auxiliary engines. These last have blades which fold together when the boat is under sail, reducing drag. Variable pitch propellers can be adjusted, either before or during use, to match their angle of attack through the water to engine speed and load.

How to choose

Choice will depend on shaft diameter, make, model and power of the engine. Compared to fixed propellers, folding models can improve performance under sail by as much as several knots. Thus, they are particularly useful when racing. Variable pitch propellers offer improved efficiency and fuel economy, since their angle of attack adapts to engine operating parameters.
