Just like cars have wheels, boats have propellers to make the move. Their main function is to rotate and provide the required thrust to make the boat move. It is a simple fan like tool using the same principle but performs are very integral role when it comes to boat performance.
Things to Factor in When Buying Props
The best way to ensure that your boat performs at its level best is buying the right propeller.
The size of the prop you are buying rely maters therefore, you should ensure that you purchase a prop of the right size. When thinking about size, you think of two things; pitch and diameter. To measure the diameter of a prop, you need to measure the distance between the hub and the end of one blade then you multiply it by two. If your vessel has a big engine, you need to go a prop with a large diameter. Every prop produces forward movements to make the boat move or accelerate, this movement is measured in inches and is commonly known as pitch. you should select a prop based on its pitch after you have considered the power of the engine that your boat has. Failure to balance these two things can cost you a lot in engine repairs.
The other important thing to factor in is the number of blades that an acme propeller has. When considering the number of blades you will not need to worry about their sizes. When you increase or decrease the number of blades in an acme propeller you also need to adjust the diameter and pitch of the prop accordingly. The most common number of blades is three and four for most props. In some cases you can interchange a three blade acme propellers with a four blade solas propellers on inboard and stern drives and you will not notice any change in the performance of the boat.
A good material used to manufacture solas propellers are durable, affordable and give ultimate performance. Boat propellers for sale are manufactured using different materials but the best ones are made using either composite, aluminum or stainless steel. If you choose a composite prop you will have to buy a new one every time when it breakdown but it is less bulky, flexible, durable and affordable. Most props made using aluminum are flexible in nature, weigh more than their composite partners, easy to repair but cost more than composite props. If aluminum and composite acme propellers do not look appealing to you, you can opt for a stainless steel prop that weighs more, less flexible, is difficult to repair and costs more.
Always ensure you consult an expert before you make any replacements to your boat.
