To get the best performance of your boat, you will need to have the right 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 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 the water is pushed behind, this works to propel 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 when you are out to buy one, and the two numbers 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 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. A low pitched propeller can create more power due to the higher engine RPMs, but your boat will 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 consideration whenever you are selecting your engine’s propeller which represents the angle between the hub and the blade. Since the rake angle determines how much bow the propeller lifts out of water, ensure that you make the right decision considering that too much rake will serve to reduce your boat’s overall performance.
When you are buying a prop, some will come with prop cups which will help create some space between the blade sides which serves to reduce ventilation and slippage as well. 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.
