Overview / What Is Amita 3 – Mercury (9.25 x 12″) Solas RH Propeller?
The Amita 3 – Mercury (9.25 x 12″) Solas RH Propeller is a premium aluminum marine prop designed to offer outstanding efficiency, strength, and hydrodynamic stability. Built using squeeze-cast technology, the propeller delivers uniform blade thickness and balance, improving water grip and reducing cavitation.
This propeller features a 9.25″ diameter and 12″ pitch, ideal for Mercury outboards in the 8–9.9 HP range. With its three-blade design and right-hand rotation, it’s perfect for boaters who value responsive acceleration, efficient cruising speeds, and enhanced control in tight maneuvers.
Propeller Blade Dynamics: Why the 12” Pitch Matters
Pitch is one of the most critical elements in propeller performance. The 12” pitch on the Amita 3 translates to higher travel distance per engine rotation, improving fuel economy and allowing boats to cruise at optimal speed with less engine strain. However, it’s essential that the engine can achieve its recommended RPM range to avoid performance loss.
Compared to lower pitch props (like the 11”), the 12” pitch offers improved top-end speed, making it ideal for lighter loads or when higher velocity is prioritized. When choosing between pitches, consult with your engine’s RPM range and your usage goals (acceleration vs speed).
How to Install the Amita 3 Propeller on Mercury Outboards
Installing the Amita 3 propeller on your Mercury engine is a straightforward process that can be completed in under 20 minutes with basic tools. Follow this step-by-step guide:
- Ensure the engine is turned off and remove the safety key.
- Straighten and remove the cotter pin holding the propeller nut.
- Slide off the nut, washers, and the old propeller.
- Inspect the shaft for debris or corrosion; clean and apply marine-grade grease.
- Install the new Amita 3 propeller, followed by the thrust washer and spacer.
- Secure with the nut and insert a new cotter pin.
Test the propeller in water at low speeds before going full throttle to ensure everything is functioning smoothly.
Maintenance Tips
Proper maintenance of your Amita 3 propeller ensures extended lifespan, reliable performance, and safety on the water. Here are some essential tips to keep it in top shape:
- Regular Inspections: Check for nicks, bends, or cracks after every boating trip.
- Grease the Shaft: Prevent corrosion and easy removal during future replacements.
- Rinse After Use: Always flush the propeller with freshwater after saltwater use.
- Tightness Check: Ensure the prop nut is secure and the cotter pin isn’t worn or missing.
- Balance Monitoring: Vibrations can indicate imbalance—inspect or replace if needed.
Routine maintenance not only enhances longevity but also protects your lower unit from costly damage.
Propeller Damage Troubleshooting and Repair Advice
Over time, even the best propellers may experience wear or accidental damage. The Amita 3 propeller is repairable under certain conditions. Here’s how to identify issues:
Common Symptoms:
- Excessive vibration or noise
- Poor acceleration or unusual fuel consumption
- Visible cracks, dents, or bent blades
Minor chips or dings can often be repaired by a marine prop shop. However, major cracks or bent hubs require replacement. Operating with a damaged prop can lead to lower unit failure, so proactive replacement is wise.
Expert Advice and Pro Recommendations
Marine professionals consistently recommend the Amita 3 – Mercury (9.25 x 12″) Solas RH Propeller for boaters who prioritize reliability, mid-to-high speed cruising, and affordability. It’s especially effective for lightweight fishing boats, inflatables, and smaller fiberglass vessels.
Keep a spare propeller onboard during long trips, and always recheck your RPM range after prop changes. Your ideal prop should allow your engine to reach its optimal wide-open throttle (WOT) range as per manufacturer specifications.

Detailed FAQ Section
What engines are compatible with the Amita 3 – Mercury (9.25 x 12″) Solas RH Propeller?
This propeller is engineered for use with Mercury and Mariner outboard engines in the 8 to 9.9 HP range. Compatibility includes 2-stroke and 4-stroke models with matching spline count and shaft diameter. Always confirm with your engine’s specifications or prop fit guide before purchasing. For custom setups or vintage motors, consult with a marine mechanic to ensure fitment.
Is the Amita 3 – 9.25 x 12″ propeller suitable for heavy loads?
The 12″ pitch is optimized for lighter boats or scenarios where top-end speed is a priority. For heavier boats or if you frequently carry passengers and gear, consider stepping down to an 11″ pitch to maintain torque and acceleration. Using the wrong pitch under load can lead to engine overwork and decreased performance. It’s all about matching prop characteristics to your boating habits.
How do I know if I need to replace my propeller?
Watch for signs like vibration, poor hole shot (acceleration), increased fuel use, or prop slippage during turns. Visual damage such as blade distortion, metal fatigue, or corrosion are clear indicators. If you’re unsure, remove the prop and inspect the hub and blades thoroughly. Routine inspection after 25–50 hours of use is a good practice to catch issues early.
Can I install the Amita 3 propeller myself?
Yes! Installation is simple with basic tools such as a wrench, cotter pin, and marine grease. Many boat owners do this as part of seasonal maintenance or after damage. Still, it’s important to follow torque specifications and propeller kit instructions. If you’re a first-time installer, watching a video tutorial or consulting a pro can offer peace of mind and help avoid costly mistakes.
What makes the Amita 3 propeller different from others?
The Amita 3 series by Solas is known for its squeeze-cast aluminum construction, delivering strength comparable to stainless steel without the high cost. It features high-gloss powder coating for corrosion resistance, precision balance for minimal vibration, and a rubber hub to absorb shock. These features make it a strong performer across freshwater and saltwater environments, backed by excellent customer satisfaction worldwide.
Conclusion
The Amita 3 – Mercury (9.25 x 12″) Solas RH Propeller, 5111-093-12 is a solid investment for boaters seeking improved cruising speed, dependable build quality, and ease of use.
