The propeller is so important because it is the hardest working part of the entire boat. This means there are more chances of your propeller being bent over time. This can be a serious issue if left unchecked. Some flexibility is important here, as it has to cut the air to create propulsion.
But it needs to be made of sturdy material to go through the number of rotations it goes through with such a massive torque behind it. However, on the other side, the torque is also directly proportional to how much time it will take to get damaged.
While the latter is a common issue, it usually takes more time to develop than the propeller itself is bent. This is a big issue, and a common way to identify it is to see if your skeg is bent.
If your fin is bent, trying to fix it yourself might not be a good idea as you can easily end up doing more harm than good. If your skeg is bent and there are vibrations, it can end up damaging most things around it—the gears, the bearings, and even the shaft.
In all kinds of boats , especially those with the propellers semi-immersed or completely immersed in water, unusual bends in the propeller or prop shafts are commonly expected.
These are usually nothing to worry about. Considering the kind of force exerted on them as a result of trying to cut through the water and the water resisting with every rotation, it becomes necessary for one to check the propellers after a certain time period.
If the propeller is not at its peak condition, you will find it difficult to fly through the waters with as much efficiency. Many experts say that you do not need to change the propeller until you see bends that are quite visible from up close and suspiciously visible when seen from a distance. More blades are smoother but slightly less efficient. The typical compromise is three blades, although four blades are becoming increasingly more popular. Blades should be as thin as possible, since it takes more power to turn a thick blade.
Stainless propellers are five times stronger than aluminum, which is why they can be thinner and still retain adequate strength. Hence, stainless-steel props are more efficient.
