The two main factors that affect the selection of a good boat propeller are the size of the propellers and the horsepower of the engine. These two factors are important to ensure optimum boat performance and the fuel efficiency of the engine. 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.
The diameter and pitch are important when selecting a boat propeller. 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 pitch should enable the boat to have maximum momentum. The best guide for the ideal diameter and pitch are the specifications given by the manufacturer of the engine of the boat. If there are no specifications, dealers of boat motors will be able to give the diameter pitch specifications for the ideal propeller for a boat engine.
The next factor to consider when selecting a propeller is the number of blades. Commonly available props come with three and four blades. The four blade propeller is faster, enables quick acceleration, faster planing, higher transom height, less slippage and better holding power. The three blade propeller gives better top end speed and is ideal for racing or speed boating. Three blade propellers can be changed to four blade propellers by reducing an inch of the pitch. The cupping of the blade is a factor to be considered. Cupping is the curve at the edge of the blade. The more the cupping the better the grip the prop will have on the water. The thickness of the blade is also a consideration. The blades should be thin enough to reduce drag and have the necessary thickness for additional strength.
The way the boat is used impacts propeller choice. .No propeller fits all types of usage. 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. It is important to keep the purpose of using the boat in mind when selecting a propeller. 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. Aluminum props are ideal for freshwater lakes and could corrode in high seas. Stainless steel is a good option for all waters because it is corrosion resistant. Stainless steel lasts longer and costs more. Composite props can be used in all types of waters and is an inexpensive alternative to stainless steel.
The brand of the propeller is an important factor. The brand should fit all types of engines. Well known propeller brands will give better performance. They will come with warranties. Some of them have lifetime blade and hub warranties. They are manufactured after strict performance tests and will work better and last longer.
