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.
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. When water is pushed to the rears; your boat moves 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. 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 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. A low pitched propeller can create more power due to the higher engine RPMs, but your boat will 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 boat props will have cups which are helpful in creating space between the blade sides and thus effectively reducing slippage and ventilation. 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.
