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. Here are tips when you are buying props for sale where you have to keep in mind the design as it affects efficiency, power and speed.

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. It is the water being pushed to the rears that help move your boat forward. The blades are designed to move in a clockwise direction, when looking from the rear side, although some boats will have a combination of two propellers, one rotating in the anti-clockwise direction, which will serve to stabilize the boat and also reduce steering effort.

Propellers are described in two numbers when you are out to buy one, and the two numbers represent the diameter, and the pitch of the propeller. Diameter represents the distance between tips of the propellers and when a propeller has a large diameter it ensures that it can push a lot of water and thus creating more power. The manufacturer predetermines the diameter, and thus you will be selecting your boat’s propeller focusing on the pitch.

When selecting boat prop based on the pitch of the propeller, you will need to choose a propeller with a high pitch as it will see your boat move faster. When you select a prop which is low pitched, it can help create more power, but it will see your boat move slower. Always ensure that an engine prop that you select will help your engine operate in the set range since going under-range will lug your boat while going over-range causes your engine to strain.

Prop rake is another essential consideration when you are selecting boat propellers and it represents the angle between the blades and the hub. It is the rake angle that determines how much bow your propeller lifts out of water and too much rake will work to strain the engine and thus affect performance of your boat.

Some boat props will have cups which are helpful in creating space between the blade sides and thus effectively reducing slippage and ventilation. With the cup on the trailing edge, it serves to increase pitch size and thus the prop can create more power at the cost of your engine speed while fewer blades enhances the efficiency of the propeller.
