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.
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. When water is pushed to the rears; your boat moves 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.
Propellers are described in two numbers when you are out to buy one, and the two numbers represent the diameter, and the pitch of the propeller. 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 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. 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 essential consideration when you are selecting boat propellers and it represents the angle between the blades and the hub. 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 boat props will have cups which are helpful in creating space between the blade sides and thus effectively reducing slippage and ventilation. Selecting props with cups ensure that pitch size is increased and thus your engine can have more power while you can also select propellers with fewer blades as they are efficient.
