What do the numbers on a propeller mean?

The numbers on a propeller generally refer to the size of the propeller. Propellers are usually designated by their diameter and pitch. The diameter is the distance from the tip of one blade to the tip of the opposite blade, measured at the widest point. The pitch is the distance that a propeller would move forward in one revolution if it were moving through a soft solid, like a screw through wood.

For example, a "14 1 4 x 21 propeller" would have a diameter of 14 ¼ inches and a pitch of 21 inches. The pitch of the propeller determines how much thrust it can produce, with higher pitch propellers able to generate more thrust. The diameter of the propeller determines how much air it can move, with larger diameter propellers able to move more air.

The size of the propeller is important because it determines the amount of thrust that the propeller can generate, which in turn affects the performance of the boat. A larger, lower pitch propeller will produce less thrust, but will be more efficient and create less drag. A smaller, higher pitch propeller will produce more thrust, but will be less efficient and create more drag.

Are aluminum propellers or stainless steel propellers better for boats?

The type of material that a boat's propeller is made of can affect its performance and durability. Aluminum propellers are typically less expensive than stainless steel propellers and are known for being lightweight and easy to handle. However, they can be more prone to damage and may not last as long as stainless steel propellers. Stainless steel propellers (such as Turning Point stainless steel props) are far more durable and resistant to corrosion, but they are also heavier and may not be as effective in some applications. In general, the best type of propeller for a boat will depend on the specific needs and requirements of the boat and its operator.

How can I select the right Turning Point Prop for my outboard engine?

Whether you’ve got a 150 hp 4 stroke Mercury outboard, Yamaha 115 hp outboard, or even a Mercury pro kicker, Turning Point offers a great resource to find a compatible propeller for your outboard, inboard, and sterndrive engine(s). Use the online tools found at the Turning Point Prop Wizard by selecting your Manufacturer, Horsepower, Model, Year, and other additional information (ie. left hand twist, right hand twist, etc.). You’ll be provided a list of compatible props for your particular engine and boat model, making the process of finding a propeller a cinch. 

What type of propeller maintenance should boaters do?

Routinely inspect boat propellers for larger knicks and make sure the blades are not bent. Also, remove the propeller every six weeks. Fishing line tends to wrap around behind the thrust washer, which can lead to a seal failure.

With a ball-peen hammer, tap the edge of the washer to knock it loose so the fishing line can be removed. When putting it back together, apply a light coating of grease on the splines.

What is the difference between right hand twist and left hand twist propellers?

The direction of a propeller's twist, or pitch, is determined by the direction that the blades rotate as they move through the water. A right-hand twist propeller will rotate clockwise when viewed from the back of the boat, while a left-hand twist propeller will rotate counterclockwise. The direction of the twist affects the way that the propeller moves through the water and can impact the boat's performance. Right-hand twist propellers are typically used on boats with inboard engines, while left-hand twist propellers are used on boats with outboard engines.

Are 3 blade propellers better than 4 blade propellers for boats?

The number of blades on a boat's propeller can affect its performance in different ways. In general, 3 blade propellers are more commonly used on boats than 4 blade propellers (such as a Turning Point 4 blade prop) because they are typically more efficient and provide better acceleration. This is because 3 blade propellers have a larger diameter and are able to displace more water, which gives the boat more thrust. 3 blade propellers are also easier to turn, which can make them more responsive and maneuverable. However, a 4 blade propeller can provide some advantages in certain situations. They are typically better at reducing drag, which can make them more effective for boats that are travelling at high speeds. They are also less susceptible to ventilation, which can be a problem for boats that operate in choppy or turbulent water. Ultimately, the best choice of propeller will depend on the specific needs and requirements of the boat and its operator.
