Guide When You Are Buying Boat Propellers
The best way to enhance the performance of your boat is by selecting the correct propeller for your boat. 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.
A propeller will have a hub which is surrounded by blades and the blades have equal length and size while they are also twisted which ensures that as they rotate they are pushing water behind. 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.
When you are buying boat propellers, they will come in description of two numbers which 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 diameter is predetermined, and thus your prop selection will rather be based on the pitch of the prop.
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. Low pitched props will help create more power for your boat due to high engine RPMs, but it will cause your boat to 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.
Prop rake is another consideration whenever you are selecting your engine’s propeller which represents the angle between the hub and the blade. Rake angle determines how much your boat’s bow lift out of water and too much rake can strain the engine and thus reduce your boat’s overall performance.
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.
