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. Props use the same working mechanism as a fan to make a boat move. Props are simple and look like a modified fan but uses the same working elements just like a simple air conditioning fan.
Key Things to Consider when purchasing acme propellers
Good props ensure that your vessel performs at its maximum.
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. Diameter of a propeller is accurately obtained by multiplying the distance between the hub and the tip of one blade by two. If your vessel has a big engine, you need to go a prop with a large diameter. Pitch can be defined as the accelerative movement produced by a propeller per one complete rotation and is quantified in inches. 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. When considering the number of blades you will not need to worry about 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. Most props have three to four 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. Stainless steel, composite and aluminum are materials used to make the best boat propellers for sale. Composite props will weigh less, are flexible, cost less but are impossible to repair meaning you will buy a new one in case of a breakdown. 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.
