- Remove the cotter pin and propeller nut from the old prop.
- Slide off the old propeller, noting washer order.
- Clean the shaft and check for fishing line or debris.
- Slide the new 5011-078-07 propeller onto the shaft with included hub kit.
- Replace washers and tighten the prop nut securely.
- Insert a new cotter pin to lock the assembly.
Pro tip: Grease the propeller shaft lightly to make future removal easier and prevent corrosion.
Maintenance Tips
To extend the lifespan and maintain the efficiency of your Amita 3 propeller, consistent maintenance is essential. Here’s what you should keep in mind:
- Inspect Regularly: Check for dings, cracks, or bent blades after each trip.
- Clean After Use: Rinse with fresh water, especially after saltwater use, to prevent corrosion.
- Check Shaft & Nut: Ensure tightness and no play in the prop.
- Grease Shaft: Apply marine-grade grease every season.
- Storage: Remove and store propeller when not in use for extended periods.
Proper care will ensure optimal performance season after season.
Performance and Durability in Harsh Conditions
The Amita 3 Mercury propeller is built for resilience. Its aluminum alloy composition withstands impacts from sandbars and minor underwater obstacles better than composite options. This makes it ideal for shallow water cruising, inland lakes, and brackish environments. Boaters who often deal with variable water depths find this model reliable and forgiving.
Furthermore, the propeller’s hydrodynamic blade profile ensures minimal drag and smoother water penetration, which translates into better fuel efficiency and enhanced maneuverability under full throttle or slow trolling conditions.

Best Propeller Options for Mercury 4-6HP Outboards
Aside from the 7.8 x 7” pitch, Solas offers a variety of Amita 3 configurations in different pitches to match specific boating needs. The 5011-078-07 is ideal for boats that require strong low-end torque and efficient planing at low RPMs.
If you want more top-end speed, you might explore slightly higher pitch versions. But for load-bearing scenarios and calm to medium water conditions, this version is often the most effective balance of thrust and control.
Troubleshooting Common Propeller Issues
Understanding common propeller issues can help prevent performance problems before they worsen:
- Vibrations: May indicate a bent blade or unbalanced propeller. Replace or repair as needed.
- Slipping: Caused by a worn hub or improper installation. Ensure hub kit is seated properly.
- Overheating Engine: Too much pitch or incorrect prop size. Downgrade to 7” pitch if over-propped.
Always match your propeller to your boat and usage style. If unsure, consult our support team for customized advice.
Detailed FAQ Section
What size propeller should I use for my Mercury 6HP engine?
For most Mercury 6HP outboard motors, the Amita 3 7.8 x 7″ is the recommended size. It provides adequate thrust and acceleration for small boats, ensuring smooth cruising and good fuel economy. However, always verify your engine’s gear ratio and boat weight to ensure the pitch is optimal. Using a 7” pitch helps when the engine struggles to reach its RPM range or when pulling loads at low speeds.
Is the Amita 3 – Mercury 7.8 x 7″ propeller easy to install?
Yes, the installation process is straightforward and suitable for DIYers. It includes the hub system, so no special tools are needed beyond a wrench and cotter pin pliers. The prop slides directly onto the shaft, and the included rubber-cushioned hub absorbs shock and reduces vibration. Make sure to follow the steps outlined in your Mercury engine manual or refer to our online installation guide for added support.
How long does an aluminum propeller like this typically last?
With proper care, an aluminum propeller can last 3 to 5 years or longer. Its longevity depends on usage frequency, water conditions (salt vs. fresh), and how often it hits underwater objects. Squeeze-cast aluminum, like that used in Solas props, offers increased durability. Regular inspections and maintenance help prevent premature wear or damage, ensuring years of reliable use.
What are the signs my propeller needs replacing?
Watch for signs like decreased speed or acceleration, higher fuel consumption, unusual vibration, or visible blade damage. If any blades are bent, chipped, or cracked, it’s crucial to replace the propeller immediately to avoid transmission or shaft damage. Another sign is if your boat fails to reach the proper RPM at wide-open throttle, indicating pitch issues or prop slip.
Can I use this propeller in saltwater?
Yes, the Amita 3 aluminum propeller is safe for saltwater use. It is built with corrosion-resistant materials and protective coatings. Still, we recommend rinsing the propeller with fresh water after every saltwater use and applying marine-grade grease on the shaft during installation. This reduces the risk of corrosion and seizing over time.
Conclusion
The Amita 3 – Mercury (7.8 x 7″) Solas RH Propeller, 5011-078-07 delivers a powerful combination of performance, ease of use, and durability. Ideal for Mercury 4-6HP outboards, it provides smooth operation and optimal fuel usage for small boats. Whether you’re navigating lakes or coastal waters, this propeller won’t let you down.
