It is undeniable that acquiring the correct propeller will definitely give the engines a longer life and will allow it to perform at its best. We could not say that a single propeller is the right or the perfect one all the time. 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. Verifying this matter with the dealer prior to buying the product is a very important thing to remember. But then, you should expect that if you already own the boat, things may already be changed. 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.
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. Diameter is also one of the basic terms that you need to know. It is certain that the blade could travel a certain distance and the diameter is the one that measures the distance that it could travel from the center point up until the distance that it could travel the the most. The next term that is also very important to know is the slip which 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. Depending on the propeller’s design and its usage, a propeller that is standard will experience 10 up to 30 percent of slip. The next one is the thickness of the blade and it is ideal to use thin ones.
