The boat propeller is a mechanical device that helps the boat to push through the water. The boat propeller pays a crucial role in the boat as this is what that determines how the boat will function. Your boat may fail to operate well; when the engine is right and has a wrong boat propeller. Thus, you are supposed to ensure that you always have the right boat propeller. The following are the points that you should look at when buying a boat propeller.
The first thing to look at is the size of the boat propeller. In this, you need to look at two things that include the diameter and the pitch. To measure the diameter you should check at the distance from the center of the hub to the tip of your boat blades which should be two times of this. The smaller diameter will require a small engine or it will be best for the fast high performing boats. The pitch involves the theoretical forward distance that is measured in inches where the boat propeller will travel for one revolution. Therefore you are supposed to purchase the boat propeller of the right size for your boat. You can click here for more info.
The next thing should be looking at the pitch. When you experience under revving or over-revving in your boat, you need to look for a boat propeller that has a different pitch. There is a close relationship between the pitch and the engine rmps. When the pitch increases, there will be a decrease of the engine rpms and also the decrease of the pitch will increase the engine rpm. When you have your boat under revving, then you should go for the boat propeller that has less pitch and thus for the over revving, the boa propeller with more pitch will be suitable
Determine the right boat propeller for you by checking at the material. There are different materials that can be used in making the boat propeller. The most commonly used material on the boat propeller is the aluminum material, the aluminum material is cheaper and they are suitable for use on the outboards. With the stainless steel material, it is more beneficial compared to the aluminum material. This is because of the thinner and stiffer bladders it has that are of advanced designs. the cost of the stainless steel boat propeller will be high but the good thing is that it will be more durable.
