The best way to enhance the performance of your boat is by selecting the correct propeller for your boat. 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. 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 when you are out to buy one, and the two numbers represent the diameter, and the pitch of the propeller. 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 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. 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. 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. 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.
