Rotational motion is converted into thrust to enable power transmission using a boat propeller. It consists of three or more blades. A pressure difference is created between the forward and rear surfaces when the blades spin. Boat performance can be enhanced by choosing a correct propeller. Selection of the correct size and style of boat prop will allow the engine to apply its maximum horsepower to the water. Smaller diameter propellers are for smaller engines and boats while larger diameter props are for larger engines and boats.
Your engine needs to operate within its rpm range and thus a propeller size that allows this should be selected Proper rpms range should maintain when changing the number of blades. When purchasing you should make sure the propellers are made of composite aluminum and stainless steel. Durability, good performance, and affordability are advantages of composite boat props. Many models and styles are available for aluminum propellers hence making the most commonly used. To acquire the best durability and highest performance, stainless steel props should be used. Cupped boat propellers are the best at efficient fuel consumption. When selecting always aim to pick a boat propeller that allows the maximum engine WOT.
If the performance of your current prop is good always choose a replacement prop that has a similar diameter. You can consider upgrading to a four blade prop rather than a three blade. Pitch and rpms are inversely related; fewer RPMs less pitch and vice versa. High pitch power props are recommended for tournament boats to achieve high speed. Lower pitch power props are recommended for houseboats and cruisers since they focus on efficiency at displacement speeds. Best engine performance for different application can be achieved using different props. Make use of two props in order to optimize the power of your engine.
The model boat propeller is the newest addition to the others. They are becoming more popular among engine manufacturers. Money can be saved when using modular props since there is no need to purchase a second prop. An extra propeller with tools on board is essential to enable you change propellers when need be. In case of a props strike or spin out a hub an extra propeller will save your time. It is advisable to always seek help in changing props when an emergency occurs. Contact professionals any time you suspect your boat is underperforming. Any attempt by you to replace a broken propeller may be fatal. In the process of selecting a propeller always pick the one that fit your boat best. A propeller with proper balance will run smoothly and produce no vibrations.
