1. SOLAS New Saturn 1431-140-11
Best Prop for 2-Stroke Engine
Specifications
- Diameter: 14”
- Pitch: 11
- Blade: 3
- Material: Stainless Steel
- Rotation: Right Hand
- Finish: Natural stainless steel silver colored
The Solas New Saturn 14″ Stainless Steel Prop turns out to be quite the performer.
First off, let’s talk about the design. The NEW SATURN 1431-140-11 Traditional Rubber hub gives the prop a solid foundation, offering you an all-around great performance.
You also get a decent acceleration with the Solas New Saturn which picks up speed quite fast. The large ear blade design is a neat feature that seems to contribute to its efficiency.
One thing that stood out to me was the smoothness of the operation. The propeller feels well-balanced, and there’s no noticeable vibration or wobbling.
SOLAS also claims to use advanced CAD, CAM, and CAE technologies to ensure top-notch precision in their products, which kind of shows in the New Saturn’s performance.
But the key selling point of the SOLAS New Saturn seems to be its durability. Compared to SOLAS 1411-130-19 Amita 3’s aluminum finish, New Saturn boasts stainless steel which makes it almost resistant against any physical damage.
Paired with 90 HP Mercury, the prop fits pretty well.
This propeller is made from stainless steel, and SOLAS seems to have gone the extra mile to make it tough.
A high percentage of chromium, nickel, and molybdenum forms their stainless steel props, which makes them resistant to rust from saltwater exposure.
2. SOLAS 1411-130-19 Amita 3
Best Acceleration and top speed
Specifications
- Diameter: 13”
- Pitch: 19
- Blade: 3
- Material: Aluminum
- Rotation: Right Hand
- Finish: Squeeze cast aluminum prop
We’re giving the second place to yet another SOLAS prop for your 90 HP Mercury. And this time, it’s the 19-pitch SOLAS 1411-130-19 Amita 3.
In contrast to SOLAS New Saturn, the SOLAS 1411-130-19 Amita 3 comes with an Aluminum build, which makes it an affordable pick for everyone. It costs one-third of what New Saturn does.
However, the squeeze-cast aluminum finish makes the prop more durable compared to other similar aluminum props in the market. It also helps the boat reach decent acceleration.
The 3-blade prop is great for reaching top speed with better efficiency than the SOLAS New Saturn, thanks to having a higher pitch.
Here’s only a drawback. Just avoid reaching critical horsepower as it can bend your SOLAS 1411-130-19 Amita 3. Also, it might not be the most durable one.

What to Consider Before Picking the Best Prop for 90HP Mercury
Selecting the ideal propeller for a 90 HP Mercury engine requires careful deliberation. Let’s look at the factors to consider before picking a prop for 90 HP Memory.
However, before we start discussing, if you want you can read on – How does mercury 2+2 work?
Build Material
Aluminum and Stainless Steel are the most preferred pick for a boat engine.
Stainless Steel props are favored for their durability and corrosion resistance. But it can cost you a lot for such assurance.
Aluminum props on the other hand are a great budget-friendly option. Although less robust, Aluminum props can be lightweight and with proper pitch, can get you great acceleration and top speed.
Number Of Blades
With 3 blades, your boat experiences better efficiency at higher speeds as it creates less drag, allowing the boat to move faster. 3-blade props are cheaper than 4-blade props and easier to maintain and install.
On the other hand, a 4-blade propeller is better for maneuvering at low-speed riding as it provides more surface area and grip in the water.
4-blade props are also highly efficient in reducing vibration and noise, allowing you to experience a smoother ride.
Pitch And Diameter
Tailor pitch and diameter to your boat’s size, weight, and engine power. Around 14” diameter and 19 – 21 pitch suits a Merquic 0.0.
Propeller Type
Less propeller pitch, more blade surface, and less rake usually help boats stay on the plane at slower speeds.
Picking the right type of propeller and design can help you to achieve optimal fuel economy for your boat.
Budget And Value
It all comes down to your budget when you’re looking for a prop for 2005 90 HP mercury.
Carefully assess your options within your budget before jumping on to your preferred prop.
Manufacturer And Brand Reputation
You’re more likely to receive quality products from a reputable brand rather than some off-brand products.
A prop is an expensive investment, and you expect it to perform its best for a very long time.
So go for a reputable manufacturer who’ll ensure superior customer support, warranties, and replacement options.
Final Verdict
That’s our 5 top picks for the best prop for 90 hp mercury. Now let’s do a recap.
SOLAS New Saturn is our best overall prop for a 90-hp mercury 2-stroke engine. The SOLAS Amita 3 is a great budget-friendly alternative with an exclusive squeeze cast process.
