If you are seeking the best way to enhance the performance of your boat, ensure that you pay attention to the prop. Irrespective of whether you are skiing or you are cruising, always ensure that your propeller can match the application as this will help maximize the performance of the boat by 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. 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.
When you are buying boat propellers, they will come in description of two numbers which 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 diameter is predetermined, and thus your prop selection will rather be based on the pitch of the prop.
When you are selecting boat prop, with focus on the pitch, it is advisable that you select a prop with a higher pitch which will help move your boat 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. 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. 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. 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.
