Boat Propeller Things to Consider.
Some of the factors that directly affect the propeller system is the engine horsepower and the size of the propeller itself since they impact how efficient the propeller works as these two factors are important to ensure optimum boat performance and the fuel efficiency of the engine and there are other important considerations for selecting a good boat prop including, size, pitch, the number of blades and the material from which the propeller is made and the diameter and pitch are important when selecting a boat propeller and the diameter is the circle made by the rotating blades and the pitch is the distance to which the boat is pushed forward at each rotation of the blades.
The engine of the boat and if there are no requirements, sellers of boat motors can give the size pitch technical specs for the perfect propeller for a boat engine and another factor to consider when choosing a propeller may be the number of blades and generally available props include three and four blades and the four blade propeller is faster, allows quick acceleration, faster planning, higher transom height, much less slippage and better keeping power and the three blade propeller provides better high class speed and is fantastic for racing or rate boating.
The thickness of the blade is also a consideration and the blades should be thin enough to reduce drag and have the necessary thickness for additional strength as the way the boat is used impacts propeller choice, well, no propeller fits all types of usage and the propeller should suit the purpose of using the boat, slow boats, speed boats, tow boats and fishing boats all require different types of propeller as it is important to keep the purpose of using the boat in mind when selecting a propeller so if the use of the boat is to be changed, the propeller should be replaced with a more suitable propeller.
The propeller should be made of durable and non corrosive material some props are ideal for freshwater lakes and could corrode in high seas some stainless steel is a good option for all waters because it is definitely resistant to any level of corrosion this steel lasts longer and costs more as it composite props can be used in all types of waters and is an inexpensive alternative to stainless steel and the brand of the propeller is an important factor and the brand should fit all types of engines some well known propeller brands will give better performance as they will come with warranties since some of them have lifetime blade and hub warranties and they are manufactured after strict performance tests and will work better and last longer.
