It is a fact that the propeller of our engine is one of the major factors that affect greatly the performance of our boat. Therefore it is necessary to be able to choose the right prop for the combination of our boat and engine.

Undoubtedly, three-blade propellers are those more commonly used in boats. Their performance is usually very good in all sectors, they normally achieve higher final speeds, they are available in a bigger variety of diameter-pitch sizes and their cost is lower.

Apart from the diameter and the pitch, also the number of the blades of a propeller, the designing interferences of the blades, as well as other variations such as the thickness of the blades, the weight of the propeller, the material are made of etc. have their own share of "responsibility" in performance of a propeller.

The second key feature along with the diameter that defines the size of a propeller is the pitch. Like the diameter, the pitch is measured in inches and it is the one we usually change so as to allow the engine to reach the maximum rpm suggested by the motor manufacturer.

By Thomas P.

The diameter and pitch are the fundamental characteristics of a propeller that determine its size. They are in any case the ''identity'' of propeller and are usually stamped on its hub.
On the hub of many propellers for example the following numbers 16΄΄ X 23΄΄ are distinguished and are measured in inches. The first number refers to diameter and the second one to the pitch of the propeller.

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.

As I was looking at the Technohull SeaDNA 999 and two of the most famous and well designed 4-blade propellers, I couldn't resist the temptation of a comparison test.
Revolution 14 5/8΄΄ x 25΄΄ against Hydromotive 14 ¾΄΄ X 24΄΄. Two propellers with approximately the same diameter and pitch would allow us to focus on the individual characteristics of their design.

Everyone knows about the Corsair’s outstanding performance levels and the acclaim it has won for itself in championship races in Greece and abroad. However, this time, for the sake of our test, we heavily overloaded one and saw that it still does great as a small ‘cargo’ carrier.
