If you are seeking the best way to enhance the performance of your boat, ensure that you pay attention to the prop. Whether you are skiing or cruising, your boat will need to have the propeller which can match the application to enhance the performance of the boat’s 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.
The propeller has a hub that is surrounded by blades which have similar lengths and size, and they are twisted to ensure that they will push water to the rear 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. 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 manufacturer will have predetermined the diameter of the prop and thus when you are buying one; you will base your selection 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. When you select a prop which is low pitched, it can help create more power, but it will see your boat 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. 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 props come with cups which help create space between the blades sides thus reducing ventilation and slippage. 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.
