If you are seeking the best way to enhance the performance of your boat, ensure that you pay attention to the 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. Here are tips when you are buying props for sale where you have to keep in mind the design as it affects efficiency, power and speed.
The propeller has a hub that is surrounded by blades which have similar lengths and size, and they are twisted to ensure that they will push water to the rear when they are turning. When water is pushed to the rears; your boat moves forward. The blades are designed to move in a clockwise direction, when looking from the rear side, although some boats will have a combination of two propellers, one rotating in the anti-clockwise direction, which will serve to stabilize the boat and also reduce steering effort.
When you are buying boat propellers, they will come in description of two numbers which 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 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.
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.
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.
