Overview / What Is Yamaha Amita3 Marine Propeller?

The Yamaha Amita3 LH Propeller (13.5 x 15”) is engineered for mid‑range Yamaha outboards, typically in the 75 to 150 HP class. Its left‑hand (LH) rotation makes it perfect for dual‑engine installations where opposing torque is needed to deliver balanced handling.

Constructed from squeeze‑cast aluminum, the Amita3 propeller offers exceptional strength, corrosion resistance, and dimensional stability. The design reduces cavitation and drag, while a polished blade surface enhances water flow. The result is smoother ride quality and reduced engine effort.

This model also features interchangeable hub kits, allowing compatibility across different spline shaft counts and hub systems. Whether you’re replacing an OEM prop or upgrading performance, it fits seamlessly into many Yamaha setups.

How to Install Yamaha Amita3 Propeller

Proper installation of the Yamaha Amita3 marine propeller ensures optimal performance and longevity. Follow these steps:

1. Turn off the engine and ensure the boat is securely moored.
2. Remove the existing propeller using the appropriate wrench, gently sliding it off the shaft.
3. Inspect the prop shaft for wear, debris, or fishing line. Clean thoroughly.
4. Apply a light coat of marine-grade grease to the shaft to prevent corrosion and ease future removal.
5. Install the new Solas Amita3 propeller onto the shaft, ensuring correct orientation (left‑hand rotation).
6. Insert the correct thrust washer and then torque the prop nut to manufacturer specifications.
7. Secure with the cotter pin and give the propeller a manual spin to check for smooth rotation without drag.

After installation, perform a sea trial. Monitor hull speed, RPM, acceleration, and handling. Ensure the engine runs smoothly without overloading or over‑revving.

Performance Benefits of Yamaha Amita3 LH Propeller

The Amita3 (13.5 x 15”) LH Propeller provides numerous performance advantages:

• Improved top‑end speed: The larger 15‑inch pitch enables higher speed potential.
• Efficient acceleration: Balanced blade loading ensures responsive throttle response and quick planing.
• Fuel savings: Reduced drag improves fuel economy during cruising.
• Reduced vibration: Precision balanced blades deliver a smoother ride.

This propeller is one of the best Yamaha Amita3 options for boating applications needing a balance between thrust and efficient cruising. It’s suitable for both freshwater and light saltwater use with proper maintenance.

Amita3 Propeller Cost and Durability Comparison

Compared to stainless steel models, the Solas Amita3 aluminum propeller is more affordable and easier to repair if damaged. While stainless steel offers superior strength, aluminium propellers like the Amita3 offer excellent cost-to-performance ratio.

Key durability considerations:

• Aluminum is lighter, which reduces rotational inertia and improves acceleration.
• Surface dings and minor impacts can be smoothed out more easily.
• Corrosion risk is higher in saltwater—rinsing and grease application are essential for longevity.

For boaters on a budget needing reliable marine propulsion, the Yamaha Amita3 marine propeller stands out for performance and serviceability.

Maintenance Tips

Routine care is vital to prolonging the life of the Yamaha Amita3 marine propeller. Follow these best practices:

• Regular inspections: Check for blade chips, dings, and bends after every outing.
• Clean the prop shaft: Remove fishing line and debris build-up around the hub and shaft.
• Grease the shaft: Apply marine‑grade grease at regular intervals and after saltwater use.
• Freshwater rinse: Always rinse the prop with fresh water after saltwater exposure.
• Storage precautions: If out of use for extended periods, remove the prop and store in a dry, shaded location.

With consistent maintenance, the Yamaha Amita3 prop can last 3–6 years or more, depending on frequency of use and marine conditions.

Troubleshooting Yamaha Amita3 Propeller

If you experience vibration, poor acceleration or cavitation after installing the propeller, consider the following troubleshooting steps:

• Inspect blade condition: Even minor bends or dings can cause imbalance and vibration.
• Check hub fit: An incorrectly fitted hub or worn splines may result in slippage or noise.
• Monitor engine RPM: If engine fails to reach recommended RPM on plane, consider adjusting pitch or switching prop size.
• Check shaft alignment: A bent drive shaft can affect performance significantly.

If correction attempts fail, consult a marine service professional to perform propeller balancing or to recommend appropriate pitch adjustments. This ensures safe and efficient operation.

Detailed FAQ Section

What engines is the Amita3 13.5 x 15 LH propeller compatible with?

The Amita 3 – Yamaha (13.5 x 15”) Solas LH Propeller 3412‑135‑15 is compatible with Yamaha outboard motors typically in the 75 to 150 HP range. Compatibility relies on correct spline count for the prop shaft and compatible hub kit. Always consult your engine’s manual to confirm propeller pitch and gear ratio recommendations. If your setup includes dual engines, the left-hand version is essential for proper counter-rotational balance. If uncertain, contact support or verify part numbers for your specific engine serial/model.

Marine professionals recommend cross-checking hub kits and splines to ensure secure installation. Solas often uses replaceable hub inserts for multi-spline compatibility. Confirm with the prop manufacturer or supplier to avoid mismatches.

How to install the Yamaha Amita3 marine propeller correctly?

To install the Yamaha Amita3 propeller:

1. Make sure the engine is off and immobilized.
2. Remove old prop carefully, check for line wrap or shaft damage.
3. Apply marine-grade grease to prevent corrosion.
4. Install thrust washer and slide prop gently onto shaft.
5. Torque nut per Yamaha specifications and secure cotter pin.
6. Rotate manually to confirm no binding.
7. Sea trial to measure performance metrics.

Monitoring top speed, acceleration curve, and mid‑range RPMs in various load conditions helps determine if the selected pitch is correct or if adjustment is needed.

What are the maintenance tips for Yamaha Amita3 propeller?

Consistent maintenance extends the lifespan of your Mercedes prop. Key points:

• Inspect after each trip for damage or debris.
• Rinse prop thoroughly with fresh water after saltwater use.
• Regularly grease the shaft to deter corrosion.
• Store off‑boat in a dry, cool environment if idle.
• Replace hub kits as needed when they wear to prevent slippage.

Incorrect storage or neglecting corrosion protection can reduce aluminum propeller lifespan markedly. With regular upkeep, expect 3–6 years or longer service life.

How does the Amita3 13.5 x 15 compare to other prop sizes?

Compared to smaller pitch props (like 13-inch), a 15‑inch pitch delivers improved top speed and cruising RPM efficiency but may reduce low‑speed thrust slightly. It suits applications where speed and fuel economy are prioritized. Against stainless steel, aluminum is easier to repair but less durable in rocky or debris‑filled waters. The Amita3 in 13.5 x 15 offers a strong balance of acceleration and fuel efficiency, ideal for recreational boats and moderate towing tasks.

Boaters needing maximum strength and minimal flex under load may opt for stainless steel, whereas the Amita3 aluminum model offers easier maintenance and lower replacement cost.

What to expect for cost and durability of Yamaha Amita3 propeller?

Pricing for the Yamaha Amita3 13.5 x 15 LH prop typically ranges in the mid‑price category for aftermarket aluminum props. Though less expensive than stainless alternatives, its durability remains high with proper care. Expect multi-year usability when following maintenance tips: rinse after saltwater, grease shaft, inspect for damage regularly. Corrosion is the main longevity threat; regular fresh water rinses and protective coatings are essential.

Overall, cost‑efficiency, ease of servicing, and solid performance make the 3412‑135‑15 model a top option within the Solas Amita3 lineup.
