How to Select Boat Propellers
Just like cars have wheels, boats have propellers to make the move. in a boat, propellers are mandated to make a boat move when the rotate the blades. When the engine of the boat is powered, propellers rotate providing a force that will keep the boat moving as long as they are rotating and the engine is on. 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.
Things to Factor in When Buying Props
The reason you need to select the best prop for your boat is to ensure that is has the best performance.
Props comes in different sizes and dimensions, the key thing here is to ensure that you buy a prop that is of the right size. The size of a prop is measured according to its pitch and diameter. Diameter is measured for the hub to one end of a blade then the distance is multiplied 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. When it comes to pitch, you need to find a balance between the engine power and the acceleration you need. 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.
The other important thing to factor in is the number of blades that an acme propeller has. As you consider the number of blades that a prop has, you will not consider 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.
When considering the material used to make propeller for sale, you should consider a material that will guarantee performance, durability and affordability. Stainless steel, composite and aluminum are materials used to make the best boat propellers for sale. 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. Stainless steel props are the heaviest, rigid, and difficult to repair but cost more than aluminum and composite props.
Always ensure you consult an expert before you make any replacements to your boat.
