1. Mercury Black Max 48-8M8029450: Top Pick
The Mercury Black Max is the factory-recommended propeller for the 115 2 stroke, ensuring proper hub fit and engine performance. In our evaluation, it delivers a solid balance of hole shot and top speed, making it ideal for general recreational boating. Owner feedback consistently praises its reliability and smooth operation at various RPMs.
However, being aluminum, it is less forgiving in rocky or debris-laden waters. If you frequently operate in shallow or rough conditions, you might consider a stainless steel option. This prop is best for boaters who prioritize OEM fit and predictable performance over maximum durability.
- OEM Mercury prop designed specifically for 115 2 stroke
- Balanced all-around performance for speed and hole shot
- Durable aluminum construction with corrosion-resistant coating
Pros: Perfect fit and warranty compatibility; Good acceleration and top speed
Cons: Aluminum can bend on impact in shallow waters
2. Turning Point Hustler 30701350: Best Value
The Turning Point Hustler offers a great balance of cost and performance. We researched owner reports and found that its aggressive blade geometry provides noticeably better acceleration than standard aluminum props. The interchangeable hub system is a plus, allowing you to switch between different outboards or pitches without buying a new hub each time.
That said, the aluminum construction limits top-end speed potential compared to stainless steel. If you primarily need a prop for watersports or frequent starts and stops, this is a strong contender. But for those chasing every last mile per hour, a stainless option may be better.
- Interchangeable hub system fits multiple outboards
- Aggressive blade design for improved hole shot
- Affordable price point with good build quality
Pros: Excellent value for the performance; Hub system allows easy pitch changes
Cons: Not as efficient at high speeds as some stainless props
3. Stainless Marine 14 x 19: Best Stainless
For those seeking top speed and durability, the Stainless Marine 14 x 19 is a standout. Based on spec sheets and owner feedback, its CNC-machined blades offer less flex and better efficiency than aluminum props, translating to higher top speeds and improved fuel economy at cruise. The stainless construction also resists corrosion in saltwater environments.
However, the premium price and lower tolerance for impacts make it less ideal for shallow or debris-filled waters. If you regularly operate in clean, deep water and want maximum performance, this prop is worth the investment. But for occasional or budget-conscious users, an aluminum prop may suffice.
- CNC-machined stainless steel for maximum strength
- Thinner blades reduce drag and increase top speed
- Corrosion-resistant and repairable
Pros: Superior durability and speed; Excellent for high-performance applications
Cons: Higher cost and less forgiving on impact
4. Quicksilver QS 13.75 x 21: High Speed
The Quicksilver QS with a 21-inch pitch is tailored for boaters who prioritize top speed over hole shot. In our research, owners with lighter hulls reported notable speed gains, especially when running solo or with minimal gear. The aluminum construction keeps weight down, aiding acceleration.
However, the higher pitch can struggle with heavy loads or when trying to get on plane quickly. If you often carry multiple passengers or gear, this prop may feel sluggish. It’s best suited for performance-oriented skiffs or runabouts that are typically lightly loaded.
- Higher pitch for increased top speed
- Quicksilver quality with Mercury compatibility
- Lightweight aluminum for quick planing
Pros: Great for light boats seeking more speed; Good build quality
Cons: Higher pitch may bog down heavier loads
5. Solas Amita 4 13.25 x 17: Best 4-Blade
The Solas Amita 4 is a four-blade propeller that excels in low-end torque and maneuverability. Based on owner feedback, it provides a strong hole shot and maintains grip during sharp turns, making it ideal for watersports like wakeboarding or tubing. The extra blade also reduces vibration for a smoother ride.
The trade-off is a modest reduction in top speed compared to a three-blade prop of similar pitch. If you rarely run at full throttle and value acceleration and handling, this prop is a great choice. But for speed demons, a three-blade design may be more satisfying.
- 4-blade design for superior hole shot and grip
- Smooth operation and reduced vibration
- Good for watersports and heavy loads
Pros: Excellent acceleration and handling in turns; Better grip in rough water
Cons: Slightly lower top speed than 3-blade props
6. Michigan Wheel Vortex 13.5 x 15: Heavy Load
The Michigan Wheel Vortex with a 15-inch pitch is designed for applications requiring maximum thrust, such as heavy fishing boats or pontoons. In our evaluation, it provides strong acceleration and maintains plane at lower speeds, which is beneficial for trolling or towing. The reinforced hub adds durability for demanding use.
However, the low pitch limits top speed and can cause the engine to run at higher RPMs than optimal, potentially reducing fuel economy. It’s best for boaters who prioritize pulling power over speed. If you often run light, this prop may cause excessive RPM.
- Low pitch for maximum pulling power
- Durable aluminum with reinforced hub
- Designed for heavy boats or loads
Pros: Great for pushing heavy loads or big boats; Affordable and tough
Cons: Low top speed; may over-rev engine if too light
7. PowerTech SCE 13.75 x 15: Budget Pick
The PowerTech SCE is the most budget-friendly propeller we evaluated. It offers a functional solution for boaters who need a replacement prop without breaking the bank. Owner feedback indicates it performs adequately for casual cruising and light loads, but it lacks the refinement and durability of more expensive options.
We caution that the materials and finish are less strong, and some users reported premature wear or bending in rocky areas. This prop is best for occasional use on calm waters or as a spare. If you boat frequently or in challenging conditions, investing in a higher-quality prop is advised.
- Lowest cost option in the lineup
- Basic design for general use
- Fits Mercury 115 2 stroke with standard hub
Pros: Very affordable; Works for basic boating needs
Cons: Lower build quality and performance; May not hold up well in demanding conditions
Frequently Asked Questions
What pitch prop should I use for a Mercury 115 2 stroke?
The ideal pitch depends on your boat weight, typical load, and desired performance. For general use, a 17-19 inch pitch is common. Lower pitch (15-17) improves hole shot and is better for heavy loads; higher pitch (19-21) increases top speed. Always check that your WOT RPM falls within the engine’s recommended range (typically 5000-5500 RPM for this engine).
Can I use a stainless steel prop on my Mercury 115 2 stroke?
Yes, stainless steel props are compatible and offer better durability and performance, especially at higher speeds. However, they are more expensive and can damage the gearcase if they hit an object, as they do not deform like aluminum. Use a stainless prop if you prioritize speed and operate in clean water.
How do I know if my prop is the right size?
Check your owner’s manual for recommended diameter and pitch. With the boat loaded normally, run at full throttle and note the RPM. If it’s below the recommended range, decrease pitch; if above, increase pitch. A properly sized prop allows the engine to reach its max RPM range without over-revving.
Is a 4-blade prop better than a 3-blade for my Mercury 115?
4-blade props provide better hole shot, grip, and smoother operation, especially in rough water. They are ideal for watersports and heavy loads. However, they typically have a slightly lower top speed than 3-blade props. Choose based on your primary use: acceleration vs. top speed.
What is the best prop for fuel economy?
For fuel economy, a 3-blade stainless steel prop with a pitch that allows the engine to run at its most efficient RPM (usually near the top of the range) is best. Avoid excessive pitch that causes lugging or too low pitch that causes over-revving. A properly matched prop will optimize fuel consumption.
Our Verdict
After researching specifications, owner feedback, and industry standards, the Mercury Black Max 48-8M8029450 earns our top pick for its OEM fit, balanced performance, and reliability. For those seeking better value, the Turning Point Hustler offers excellent acceleration at a lower cost. If top speed and durability are paramount, the Stainless Marine 14 x 19 is the runner up.
