Factors to Consider When Purchasing Boat Propellers

If you are seeking the best way to enhance the performance of your boat, ensure that you pay attention to the prop. Regardless of whether you are cruising or skiing, you will need to have a propeller that matches your application thus maximizing the power of your Engine. The following factors are essential when you are out to buy boat’s prop as selecting a prop with them in mind will ensure that your selection will enhance speed and power being efficient.

A boat propeller will have a hub which will come surrounded with blades which are built in the same length and size while they are also twisted as a measure to ensure that they will be pushing water to the rears when they are turning. When the water is pushed behind, this works to propel your boat forward. When you are viewing the blades from the rear, you will notice that most rotate in clockwise directions although some boats will have two propellers where the propellers rotating in the anticlockwise direction help stabilize your boat and also ensure that you reduce your steering effort.

Propellers are described in two numbers which represent the diameter of the propeller and its pitch. It is advisable that when you are selecting the boat prop you select one with a large diameter, distance between the tips of the blades, as they can push large amount of watr behind and thus move your boat forward by creating more power. The diameter is predetermined, and thus your prop selection will rather be based on the pitch of the prop.

When selecting the boat propeller basing your selection on the prop pitch, ensure that you select a higher pitched prop as it helps your boat move faster. A low pitched propeller can create more power due to the higher engine RPMs, but your boat will move slower. When you are selecting the props, ensure that your choice will help keep your boat’s engine RPMs in the recommended range since cases of under-range will see your boat lug while going over-range will strain your engine.

When you are buying a propeller for your boat, you will also need to choose one having considered the prop rake which is the angle between the hub and the blades. Since the rake angle determines how much bow the propeller lifts out of water, ensure that you make the right decision considering that too much rake will serve to reduce your boat’s overall performance.

Some props come with cups which help create space between the blades sides thus reducing ventilation and slippage. When you select props with cups, they will help increase the size of the pitch and thus create more power while you can also select a prop with fewer blades as they are more efficient.
