Boat Propellers and Pitch

If you are looking at investing in a new propeller, two words that instantly come to mind are propeller pitch. Being able to understand these two words ensures that you upgrade to the right kind of propeller. Let us start with the basics -- a propeller is a device that is made up of two blades that create a force that propels the likes of boats and aeroplanes ahead. A pitch is the displacement that happens to a propeller when it finishes a complete spin. Every inch of the pitch translates to the same amount of inches the propeller will advance at the end of a spin.  The experts at Propeller Depot can easily explain pitch and how it relatest to your boat prop.

This concept of a pitch is not merely for propellers but rather every mechanical device that has screws holding it together. If you are dealing with a screw of 15mm pitch, it will move 15mm forward at the end of every spin. In the creation of the propeller, it is absolutely essential that the pitches as well as the diameters are measured accurately.

If the pitch ends up being too big for a particular HP, the weight of the propeller increases and it will require more power from the engine, which it may not be able to attain. In the same manner, if the pitch is small, then the propeller becomes too light for the engine's power to be absorbed in full.

If you want to arrive at the right pitch, you have to take into consideration the power as well as the rpms of the device. Gear reductions is essential as is the size of the vessel and its application. For example, a yacht will need higher velocity than a tugboat. It is based on this that engineers will be able to come up with the right pitch for the vessel.

Should you be reworking the pitch on a leisure boat, then do keep in mind that for every inch of pitch, you are working on approximately 200 rpm. As you go lower on the pitch, the rpm will increase and the other way around as well. The way to achieve the right proportion is to find a prop that will work at the best required acceleration and speed. Getting an experienced dealer to handle this for your boat is a good idea. Some of the basics he will need to know are the weight of the boat, the kind of hull it has and what its HP rating is. All of this will help you get the exact propeller pitch you need.
