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. The effect of using the same propeller in this manner is very negative because it could damage your engine’s performance in the amount of time that you would not expect. Buying the package that is combined is actually a good thing because your dealer will be responsible in giving you the right propeller that will be matched with it. 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. You should know that this criteria is very important and planning to put items that have heavy load could alter it.
In order to understand what boat propeller really means, it is very important to know and learn the basic terms that are involved with it and that is the main goal of this article.
The first basic term that you need to know is the pitch. 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. The next one is the diameter. 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. You have already learned about the pitch, now it is time to know the slip which is connected with it. 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. Well, it is expected that a propellers that is considered standard will have at least 10 up to 30 percent of slip and it will be based on the propeller’s design and will depend on its usage. One of the terms that is being used in boat propellers is the blade thickness and when it comes to choosing it, it is always ideal to choose the one that has the thinnest blade.
