Propeller analysis
There is no doubt that the propeller is one of the most important factors that can make great difference in our boat's performance. Knowing the parts of the propeller, we will be better able to understand how a propeller works and going a little bit further by knowing its basic features, we will be able to choose the most suitable one for our needs.
Hub
The hub of a propeller is the “center round barrel” to which the propeller blades are attached.
On “through-hub exhaust propellers” we distinguish the Outer and the Inner Hub which are connected together by the Ribs. In these propellers the engine's exhaust gases pass among the outer and the inner hub.
