The best way to enhance the performance of your boat is by selecting the correct propeller for your boat. 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. 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. Blades turn in the right-hand direction, when one looks from the rear side, although some boats will have two propellers where one rotates in the left-hand direction and the two propeller help 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. 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 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.
