How to Select Boat Propellers
Propellers are very essential when it comes to powering a boat. Their main function is to rotate and provide the required thrust to make the boat move.

Key Things to Consider when purchasing acme propellers
The reason you need to select the best prop for your boat is to ensure that is has the best performance.
The size of the prop you are buying rely maters therefore, you should ensure that you purchase a prop of the right size. size is determined by the diameter and the pitch of the propeller. 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. However, smaller engines goes hand in hand with props that have small diameters because they have less rotational power. 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. If you select a prop with a pitch that does not directly corresponds to the power of the engine, you will end up having engine failures.
You also need to consider the number of blades that a prop has. As you consider the number of blades that a prop has, you will not consider their sizes. However, when you think of changing the number of blades in a solas propeller, you will need to adjust the pitch and diameter of the said prop. Many boat propellers for sale have four to three blades but there are other with more blades. 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.
The quality of the prop will be measured in terms of its durability, affordability and performance hence a material that guarantees all these should be considered.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. For aluminum acme propellers; their weight is average, flexible and easy to repair but cost more than composite propellers. 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.
It is wise to always work with an experts when it comes to prop replacements.
