It is very important to have the right propeller if you aim to give your engine a longer life and an extraordinary performance. However, it should also be noted that not all the time, a single propeller is always the right one. It is understandable that there will be times wherein the propellers should absolutely be changed especially when you are planning to use it in a different way than how it used to be. Your boat engine could be damaged quickly if you insist to use the same propeller in this situation. It is expected that the dealer from whom you bought your boat from, should see to it that the propeller that comes with it is the correct one especially if you have bought it together as a package. That is why, prior to buying it, you must make sure that you verify this matter with the dealer. There are instances that these things may be changed the moment that you already own the boat. There are certain factors on how the dealer chooses the right propeller for your boat and one of them is basing it on the load that your boat could manage. Well, that is one of the most important criteria however, it is also possible that it could be altered especially when you add some items on it that are heavy.
This article was made to make you understand what does boat propellers really mean and in order to do that, let us go through with the basic terms first.
Pitch is one of the most important terms that is being used when it comes to boat propeller topics. The pitch is basically the one that measures the distance that the boat propeller travelled and how fast did it travel forward and backward. Just like the screw which tries to penetrate the water by turning, the propeller also looks like that. Diameter is also one of the basic terms that you need to know. From the center point up to the distance that the blade could travel the most, the distance is being measured and that is called the diameter. Slip is also one of the terms that is being used in boat propellers and it is connected with the pitch. It is because of the fact that the pitch, which is defines as the distance that being travelled by the propeller, could definitely be affected when there will be slippage that will happen on the process. Having a slip of 10 to 30 percent is expectable when it comes to the standard propeller however, it will still depend on the design that it has and its usage. The blade thickness is also being used in boat propellers and it is recommended to use the thinnest blade.
