Best Prop for Mercury 150 4-Stroke: Top 5 Props (6)

1. Quicksilver Black Diamond

  • Number of blades: 3
  • pitch: 19

Product overview

The first product I will review is the Quicksilver Black Diamond Propeller. This is a very highly rated propeller with many benefits. It is very popular with boat owners. Let's see the specifications at a glance.

The propeller is made of aluminum. Aluminum is a very powerful material. It is perfect for boat propellers. Aluminum is very light in weight. So, the propeller made from it will be light. This is useful for Mercury 150 engine performance.

Aluminum is also very corrosion resistant. This property gives a great advantage in the case of propellers. The propellers are used underwater. They are therefore very susceptible to corrosion. The use of aluminum reduces the rate of rust formation.

As a result, the propeller lasts a long time. In addition, aluminum is also a ductile material. Ductility reduces the brittleness of the material. This makes the propellers strong enough to withstand light to medium hits. This is very beneficial for the boat.

The number of blades in the Quicksilver Black Diamond is 3. These blades are beautifully designed. They have a high level of efficiency. These blades also ensure a stable ride. The smaller aspect ratio gives the boat more speed.

However, you have to sacrifice fuel economy. The fuel consumption of 3-blade propellers is higher than others. The contact surface between the blade and the water is also smaller due to the 3 blades. But this situation will not cause much trouble.

The pitch of the Quicksilver Black Diamond Propeller is 19. This is a high pitch ratio. The pitch of the propeller indicates the distance that the propeller travels in one revolution. Higher pitch means more top speed.

So the Quicksilver propeller increases your speed. But the acceleration is less in a higher pitch. So you will have to consider that. But overall, the Quicksilver Black Diamond Propeller is an excellent choice for your Mercury 150 engine.


  • The installation process is very simple.
  • Propeller durability is second to none.
  • The propeller is rust resistant.
  • Variable sizes are available.


  • The hub of the propeller is not included.

Product overview

Now we come to our second product. The next product I have is the Qiclear 148-832830A45 Moto Propeller. This is also an excellent choice for the Mercury 150 4-stroke engine. The propeller fits the motor exactly. It also delivers stable high speed.

This propeller is made of aluminum. So it gets all the positive factors of the popular metal. The propeller is very light. The reason for this is the low density of aluminum. The low weight is advantageous as it reduces fuel consumption.

In addition, rust does not easily form on the Qiclear propeller. This is also due to the aluminum manufacturing material. Aluminum is very resistant to corrosion. Because the propeller runs underwater, the rust resistance is very convenient.

An ideal propeller is very break-resistant and lasts a long time. The manufacturer also worked on increasing the strength of the propeller. The propeller has undergone heat treatment to ensure toughness. So the propeller is not brittle.

The surface of the propeller is constructed with great care. The five-layer processing of the surface increases durability. In order to achieve this property, the vacuum casting process was used. All these processes and layers have increased the quality of the propeller.

The propeller comes with 3 blades. The performance of 3-blade propellers when increasing speed is excellent. But Qiclear 3-blade props are weak when it comes to increasing acceleration. This case smiles for all types of 3-blade propellers.

The installation process of the Qiclear propeller is quite simple. It comes with the necessary kits. That means you get the hub with the propeller. This reduces the installation effort many times over. This propeller is a very good choice for DIY enthusiasts.

The pitch of the Qiclear 148-832830A45 Moto Propeller is 19. That means the distance it travels in one revolution is 19 inches. This is a very high pitch compared to other propellers. Because of this, the maximum speed of the propeller is very high.


  • The installation kit comes with the propeller.
  • High-quality construction materials are used for the propeller.
  • Comes with a 1.5 year warranty.


  • Sometimes the propeller bolt does not fit.

Product overview

Now it's time to review our third product of the day. The next product I have is the SOLAS 1513-145-17 Amita Propeller. This clockwise rotation system propeller is highly regarded. The performance of the propeller is remarkable.

SOLAS Science and Engineering Corporation manufactured this propeller. They did their best to make a highly functional product. And they successfully achieve their goal. The propeller is made of aluminum. The processing quality of the propeller is therefore out of the question.

There are four layers of paint on the surface of the propeller. This is extremely helpful in preventing corrosion from water. The propeller was built using the squeeze-cast system. This casting system gives the propeller a good surface texture.

The manufacturer of SOLAS Amita Propellers claims to use high quality materials. The blades are thin. Despite this, they are hard and difficult to break. The propellers deliver consistent and efficient power to the boat. The blades are also properly balanced.

SOLAS 1513-145-17 comes with 4 blades. 4-blade propellers are good for increasing acceleration. However, the speed of these propellers is comparatively low. The 4-blade design also increases the contact area of ​​water and blades.

The pitch of SOLAS propellers is lower than that of the other items checked. It has a pitch of 17 inches. That means the blade covers 17 inches in one revolution. Because the pitch is low, the maximum speed of the propeller is lower.

This protects the engine from unnecessary stress. This is beneficial for engine health. Fuel consumption will also be low. This increases the overall efficiency of the boat. Also, the hole shot is better with low-pitch propellers.

The performance of the propeller is in the middle. It has a great handling mechanism. The rear lift is also of high quality. Overall, the propeller fits the Mercury 4-stroke engine quite well.


  1. The acceleration values ​​are very good.
  2. You will receive the hub needed for installation with the propeller.
  3. The low pitch is useful on many occasions.


  • The performance is in the middle.

4. Turning point propeller 31502112

(Video) SpitFire Propellers by Mercury Marine

  • Number of blades: 3
  • pitch: 19

Product overview

Let me discuss the second to last product on the list. Now I have the Turning Point Propeller 31502112 in my hands. This propeller is more exceptional than the other products I have reviewed. The reason for this is the construction material of the propeller.

The Turning Point Propeller is made of stainless steel. Whereas the previously discussed propellers were built out of aluminum. The stainless steel gives the propeller an aesthetic look. The propeller looks more stylish and attractive.

This can be useful for many buyers. In addition, stainless steel also has high corrosion resistance. So the stainless steel propellers are durable. This corrosion resistant property is a must in water.

Otherwise the propeller will deviate in a short time. Stainless steel is also easy to clean and maintain. So the user can easily keep the aesthetics of the propeller. Even after long-term use, the propellers can only be made new by polishing.

The Turning Point Propellers are also very durable. Stainless steel is one of the strongest metals on the market. The propeller made from it withstands the high water power. You don't have to worry about strong water waves.

Turning point propellers have a high pitch of 19. This is the distance the propeller travels in one revolution on a soft solid. This allows the motor and propeller to reach a high top speed. Manufacturers kept the balance with speed.

So controlling the propellers is not very difficult despite the high speed. This propeller comes with 3 stainless steel blades. 3-blade propellers are very efficient in increasing the boat's speed. But the increase in acceleration is less with this propeller.

The Turning Point Propeller originated in Taiwan. It only weighs 12.75 pounds. The load on the motor is therefore not very high. This propeller can be suitable for your Mercury 150 4-stroke engine.


  • Propeller hole shots are very fast.
  • High-quality stainless steel is used as the manufacturing material.
  • The operating vibration is very low.


  • The acceleration rate is low.

Product overview

It's time to discuss the last product on my list. The last propeller also comes from Turning Point. However, the Turning Point Propellers 21431930 is very different from the previous model. These two propellers are completely dissimilar in every factor.

In contrast to the previous model, this propeller is made of aluminum. Aluminum is also a good choice for boat propellers. Aluminum is a very durable light metal. So the propellers are also light. This is necessary for the smooth operation of propellers.

In addition, aluminum works very well in preventing rust. This is how the propeller works under water without the risk of corrosion. Aluminum is also a suitable metal for handling heavy loads. The life of the propeller is very long for this reason.

The number of blades in this propeller is 4. This is more than the previous version. The 4-blade propeller is very functional to increase the boat's acceleration. But the speed gain is less with this type of propeller. So you have to keep that in mind.

The pitch of this propeller is 19. So the top speed is very high. The clever design of the propeller helps keep balance. Turning Point 21431930 is very suitable for water sports. So you can easily use this propeller with Mercury 150 engines.


  • The propeller is strong.
  • high performance.


  • Sometimes the paint comes off.

shopping guide

I think now you can easily make your choice. To help you further, I will discuss the factors that you need to check when making a purchase.

number of blades

The number of blades is very important for propellers. This number plays a significant role in the speed and acceleration of the boat. So choose the number of blades according to your priority.

pitch number

Pitch number is another important aspect of any propeller. The user can use the pitch numbers to make thoughts about top speed and balance. Be careful when choosing this number. Too high or too low a pitch number is not helpful when boating.

building material

The material from which the propeller is made is very important. Because the durability and weight of the propeller depend on it. In addition, high-quality materials protect against corrosion and durability.


The diameter of the propeller determines the overall speed of the boat. Normally, fast and small boats have small diameter propellers. And for large and heavy ships, a large diameter is needed. So be careful with this aspect.

Follow this buying guide to make the best decision for you. Be sure of your preferences and then decide on a propeller for your Mercury 150 4-stroke engine.

Is 3 or 5 blade and better? ›

When it comes to design and aesthetic look, the 3 bladed ceiling fan is more pleasing than the 5 bladed. However, the 5 blades can generate more wind because the blade to blades distance is nearer, thus the wind it produces is more consistent.

How many shaves does a 5 blade last? ›

Ideally, you want to change your razor blade after 5-10 shaves. Gillette actually recommends 5-7 shaves, but this is just a general rule and it actually comes down more to the thickness and density of your facial hair.

How many blades is a better shave? ›

With a multi-blade razor or shaver, the first blade catches the hair, dragging it in the right direction, while subsequent blades cut the hair. This means you need a minimum of two blades to create an effective and close home shave.

What number of blades is best on a razor? ›

Your hair may determine the number of blades you choose. If you have soft hair, a single-blade razor will be suitable. It can easily cut soft hair below the skin's surface. If you've thick and coarse hair, go for a razor with three to five blades.

What is the number 1 razor? ›

Final Verdict. Our best overall pick is the Gillette Venus Platinum Extra Smooth Razor, which features an ergonomic handle, pivoting head, and moisture strips for a close, clean shave. If you're on a budget, consider the Nylea FlexShave 6-Blade Razor, which has a six-bladed head for precision shaving.

Hence, more number of blades can cut the hair closest to the skin, and this will help you achieve a close and clean shave. Simply put, more blades definitely help give you a closer shave.

Why is more blades better? ›

Naturally this is subject to the law of diminishing returns, but a razor with more blades also distributes the pressure of the blade cartridge more evenly. There is some evidence that this keeps your skin flatter so that you get a more even shave and less chance of nicks and cuts.

Does more fan blades mean more air? ›

Scientifically speaking, as the number of blades go up, the ceiling fan will become quieter and circulate less air. This is due to the fact that additional blades increase the drag on the ceiling fan motor and slow it down.

Which fan gives more air 3 blade or 4 blade? ›

So, it is ideal to find three blade ceiling fans for optimum airflow that works with lesser friction. Four-blade fans are for that reason, used as a supplement to an air conditioner, circulating the cool air of the AC all over the room.

Do 3 blade ceiling fans work as well as 5 blades? ›

There is a common misconception that five ceiling fan blades work better than four or even three blades. Homeowners assume that five blades means better air movement, circulation, and less cooling costs, but in reality, all five blades do is add aesthetic appeal.

Are plastic or metal fan blades better? ›

However, neither metal nor plastic fans cool better than the other. This is because, in terms of cooling a room, the number of fan blades, the diameter, and the number of rotations determines how effectively a ceiling fan cools a room.
