To get the best performance of your boat, you will need to have the right 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. 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. 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.
Propellers are described in two numbers which represent the diameter of the propeller and its pitch. Diameter describes the distance between the tips of your propeller’s blades and it is advisable that one selects a propeller that has a large diameter as it will help them push large volumes of water behind and create more power to move your boat. 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 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 the prop you select will keep the engine RPM in the recommended operating range as going under range can leave your boat lugging while going over the range will strain your engine.
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 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.
