1. Quicksilver Nemesis 8M0055535

Best Overall Propeller for 5.0 Mercruiser

Quicksilver Nemesis 8M0055535


  • Diameter: 14”
  • Pitch: 19
  • Blade: 4
  • Material: Aluminium 
  • Rotation: Right 
  • Finish: Glass phantom black finish

Quicksilver Nemesis 8M0055535 will take your boating experience to a new height with its optimal diameter and pitch range for the 5.0 Mercruiser engine. Nemesis 8M0055535 has a diameter of 14″ and a pitch of 19. 

Due to its pitch, this prop will provide a more powerful holeshot than Solas Rubex and Turning Point props. This prop has four blades. As a result, unlike its competitors including Quick Silver Black Diamond and Solas Rubex, it will provide a better handle at a lower speed. 

This prop is also specially designed to perform without any loss in top speed. Compared to its competitor Black Diamond 3-blade, it provides 16-25% faster acceleration and better top speed handling. So, get ready for an adrenaline-pumping burst. 

My favorite part about this prop is its Glass phantom black finish. This finish makes the prop look chic and it’s easy to maintain. This prop is also less expensive than Black Diamond and Solas props. 

However, there is one tiny drawback of this prop. Some users reported vibration from the propeller while running it at a higher speed.


  • Provides powerful holeshot
  • Fast acceleration
  • Better handling at a lower speed
  • Easy to maintain


  • May vibrate at a higher speed
  • Hub comes separate

2. Quicksilver Black Diamond QA3182R

Best For Reliability And Acceleration

Quicksilver Black Diamond QA3182R


  • Diameter: 14 ½”
  • Pitch: 19
  • Blade: 3
  • Material: Aluminum
  • Rotation: Right 
  • Finish: Die-cast design, black finish

If you are looking for an aftermarket propeller, there is no doubt, the Black Diamond is one of the most reliable ones. And the Black Diamond QA3182R is the best prop for Mercruiser 5.0 Alpha One. It can handle outboards and a sterndrive engine up to 250 HP.

Just like the Nemesis one, it also has a 19 pitch that is perfect for powerful holeshot than Solas Rubex and Turning Point props. As a 3-blade design, it will provide better efficiency and top-end speed than its competitor Turning Point. 

The die-cast finish gives the propeller the right amount of strength and hardness. This prop is specifically designed for use with 4-3/4″ gearcases and features a thru-hub exhaust. This makes it compatible with a wide range of outboard engines and outdrives including Mercruiser.  

However, you will get a 15% to 20% lower acceleration from this propeller than its competitor Nemesis. And the Bushing kuts of this prop don’t come with it, so you have to buy them separately. 


  • Reliable brand name
  • Durable and strong 
  • Better efficiency
  • High top-end speed


  • Lower acceleration than competitors 
  • Bushing kits come separately. 
  • Hub comes separately

3. Solas Rubex  9531-140-21

Best for Durability and Thrust 

Solas Rubex  9531-140-21


  • Diameter: 14”
  • Pitch: 21
  • Blade: 3 
  • Material: Stainless steel 
  • Rotation: Right 
  • Finish: Natural stainless steel silver colored

The next one on our top pick list is Solas Rubex  9531-140-21. The stainless steel material of this prop makes it more durable and stress-tolerant than aluminum propellers like Nemesis, Black Diamond, and Turning Point. 

Moreover, due to the material, the performance of this propeller is also superior to propellers made with aluminum. 

The unique cupping type design of the blades provides it with a greater stern lift. As a result, it provides a more powerful thrust than its competitor Quicksilver and Turning Point.

Like these competitors, this prop doesn’t need any separate hubs as it comes with a special kind of pressed-in rubber hub. Due to its higher pitch than Nemesis and Black Diamond, this propeller will help your boat speed quicker. 

However, the main drawback of Solas Rubex comes with this feature as well. As this prop is 21-pitch, The holeshot will be less powerful than a 19-pitch prop like Nemesis. Another drawback is, due to the higher-quality material, the price range of this prop is also very high.


  • High-quality material makes it more durable
  • Provides powerful thrusts
  • Speeds up quickly 
  • Don’t require separate hubs


  • Less powerful holeshot

4. Solas HR Titan 3553-141-19 

Strongest and Most Powerful Prop for 5.0 Mercruiser 

Solas HR Titan 3553-141-19 


  • Diameter: 14 ⅛”
  • Pitch: 19
  • Blade: 4
  • Material: Stainless Steel 
  • Rotation: Right 
  • Finish: Original stainless steel color 

The durability and strength provided by Solas made me keep another Prop of this brand on my list. The Solas HR Titan is an excellent choice for your 5.0 Mercruiser if you want a power holeshot, unlike the Solas Rubex. The holeshot power is ensured by the 19 pitch of this prop. 

Usually, 4 blade props come with less cruising speed. But unlike Turning Point, the Solas claim that the cruising speed is not compromised here and you will get excellent holeshots as well. This prop also comes with great fuel efficiency. 

Also, unlike Solas Rubex, it has 4 blades, which ensure better handling at a low speed. And the durability, blade strength, and thrust power are similar to the Solas Rubex. Because they are both made with almost similar technology. 

Of course, the price tag is a big drawback of this prop. Otherwise, this is one of the best props for Mercruiser 5.0 MPI.


  • Durable and strong blades
  • Powerful holeshot
  • Better handling
  • Powerful thrust 
  • Great fuel efficiency


  • You might find it a bit pricey

5. Turning Point 21502131

Best Budget-Friendly Prop for 5.0 Mercruiser 

Turning Point 21502131


  • Diameter: 14”
  • Pitch: 21
  • Blade: 4
  • Material: Aluminum 
  • Rotation: Right
  • Finish: Squeeze cut aluminum 

For today’s final pick, I am introducing the Turning Point 21502131 propeller. Its 14″ diameter and 21 pitch are optimized for exceptional thrust and speed that will be a perfect companion for your 5.0 Mercruiser. 

One of the standout features of the 21502131 propeller is its tuned vents. Due to this vent, it delivers a faster holeshot and quicker acceleration unlike its competitor Solas Rubex. 

The squeeze-cast aluminum construction of the 21502131 propeller provides added strength. It ensures that, despite being an aluminum blade, it can withstand the adversity of the marine environment, unlike its strongest competitors like Nemesis. 

This is also the cheapest prop among all these props mentioned here. 

The main drawback of this prop is its limited availability, especially outside the USA market. Moreover, the top-end speed of this prop is not very impressive. And despite being fast, the holeshot is not very reliable. Also, you have to buy the hubs separately to install this Prop.


  • Strong blades
  • Fast holeshot
  • Strong thrust 
  • Budget-friendly 


  • Limited availability 
  • Low top-end speed
  • Unreliable holeshot
  • Have to buy hubs separately

6 Factors To Choose The Best Prop For 5.0 Mercruiser

When it comes to choosing the best propeller for your boat engine, there are several things you have to consider. Let’s discuss those. 

Propeller Material

Propellers are usually made from aluminum or stainless steel. Aluminum props are more affordable but they are less durable. Stainless steel props are more durable and resistant to corrosion but tend to be more expensive.

Number Of Blades

Propellers can have three or four blades. Four blades usually provide better handling at lower speeds and may offer a smoother ride. However, they can also reduce top-end speed slightly. Consider the trade-off between acceleration and top speed based on your boating preferences.

Pitch And Diameter

The optimal pitch and diameter depend on your boat’s size, weight, and engine power. For 0.0 Merquic around 14” diameter and 19 – 21 pitch is perfect. 

Propeller Design

Look for design features such as cupping, rake, and ventilation. The unique designs increase durability and help the prop to provide more powerful thrust. 

Budget And Value

Consider your budget and the overall value of the propeller. While it’s important to find a propeller that suits your needs, balancing performance, durability, and cost is also crucial.

Manufacturer And Brand Reputation

Look for well-established companies known for producing reliable and high-quality propellers. A reputable manufacturer is more likely to provide better customer support, warranties, and replacement options.
