Are Mercury and Yamaha props interchangeable?

Mercury and Yamaha both make a wide range of boat propellers, and in some cases, it may be possible to use a propeller made by one manufacturer on a boat that was originally equipped with a propeller made by the other manufacturer. However, there are many factors to consider when selecting a propeller, and it is generally best to use a propeller that is specifically designed for your boat and motor.

For example, Mercury V6 prop will fit Yamaha F150 or larger - however, you will need the correct thrust washer, as a Mercury prop uses a different thrust washer than Yamaha. For this, PartsVu sells hub kits that include the correct insert for the hub of the prop, as well as a prop nut, new thrust washer, and other necessary hardware.

Why are boats right hand drive?

Boats are typically built with right-hand drive (RHD) for a few reasons.

One of the main reasons is that the majority of boating is done in the northern hemisphere, and most boats travel in a clockwise direction. When a boat is traveling in a clockwise direction, the propeller is spinning counter-clockwise. With a right-hand drive setup, the propeller is on the right side of the boat, which allows for better steering and maneuverability.

Additionally, having the propulsion on the right side of the boat makes it easier for the captain to keep an eye on the propeller and its surroundings, allowing them to better avoid underwater obstacles and other boats.

Another reason is the design of the engine room. The engines of the boats are placed on the right side, and the propeller is connected to the engine through a shaft. This is also more efficient and practical layout.

It's also worth mentioning that while most boats are right-hand drive, there are also left-hand drive (LHD) boats available, typically used in a counter-clockwise boating direction in the southern hemisphere or for special purposes such as high-performance boats or racing boats.

Overall, the choice of RHD or LHD for a boat is mainly driven by engineering and practical considerations.

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 14.5 x 19 propeller stainless with the designation "14.5 x 19" would have a diameter of 14 inches and a pitch of 19 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.

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

Whether you’ve got a 150 hp 4 stroke Mercury outboard, Mercury 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 is the difference between right hand twist and left hand twist propellers?

Right hand vs Left hand propeller - what’s the difference?

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 (also called a “right hand prop” or “right handed prop”) will rotate clockwise when viewed from the back of the boat, while a left-hand twist propeller (also called a “left hand prop” or “left handed prop”) 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 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, 4 blade propellers 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.
