Overview / What Is Amita 3 ‑ Volvo Penta Aquamatic (15 x 15″) Solas LH Propeller, 8712‑150‑15
The Amita 3 ‑ 15 x 15″ LH Propeller is part of Solas’s aluminum three‑blade propeller series, engineered specifically for Volvo Penta Aquamatic sterndrives. With a 15″ pitch and 14.8″ diameter matching Volvo spline and hub specifications, this model offers improved acceleration, early planing, and balanced top‑end cruising efficiency.
Belonging to the broader Aluminum Propellers | Propulsion > Propellers > Outboard > Amita 3 category, the 8712‑150‑15 fits boaters looking for durable, cost-effective propulsion upgrades. It’s suitable for various AQ models (4.3L, 5.0L, 5.7L) in both single and twin-engine configurations where left-hand rotation is required.
Design and Engineering Highlights
The Amita 3 propeller marine design balances performance and reliability. Key features include:
- High‑quality cast aluminum with anti-corrosion coating
- Three‑blade geometry optimized for reduced vibration
- Left-hand (LH) rotation to counter engine torque in twin-engine setups
- Moderate rake and cup design improving water grip and cavitation resistance
Its 15″ pitch offers excellent torque for towing or heavily loaded boats, while still achieving respectable top speed. The moderate diameter couples with the Aquamatic hub interface for precise alignment and minimal slip.
Performance Benefits and Real‑World Scenarios
Boaters choosing the Amita 3 15 x 15 prop report faster hole shots, smoother planing behavior, and reduced fuel burn when drifting or cruising at mid-range RPMs. The balanced pitch and diameter combination maintain RPM within optimal ranges for most Volvo engines, resulting in efficient thrust and steady top-speed capabilities.
For twin-engine vessels with LH/RH pairing, this LH propeller helps balance torque, enhancing straight-line tracking and steering consistency. Fishermen, day-cruisers, and light-commercial vessels benefit significantly from this prop’s versatility across load and speed demands.
How to Install the Amita 3 (15 x 15″) Propeller
Understanding how to install the Amita 3 Volvo Penta propeller ensures safe and efficient use. Begin by placing the boat on lift or trailer and shutting down the engine. Remove the cotter pin and nut from the old propeller, slide it off, then inspect and clean the prop shaft thoroughly.
Apply marine-grade grease to the splines. Align the propeller (8712‑150‑15) with the shaft, slide it on, reattach thrust washer and nut, torque to manufacturer specifications, and replace the cotter pin. Confirm the prop rotates freely before launching.
Amita 3 Propeller Marine Maintenance Tips
Proper maintenance extends propeller life and performance. Key tips:
- Inspect blades after each trip for dents, bends, or cracks.
- Rinse thoroughly with fresh water after saltwater exposure.
- Clean around the hub to remove debris or fouling.
- Grease shaft regularly to prevent corrosion and ease removal.
- Store spare propellers in a dry, protected environment.
Address minor damage promptly to avoid vibration and thrust loss. These Amita 3 propeller marine maintenance tips help maintain reliable propulsion trip after trip.
Troubleshooting RPM and Efficiency Problems
If your boat struggles to reach recommended RPM or exhibits vibration, this may signal pitch mismatch, blade damage, or ventilation. For example, a propeller overspeeding but stalling early suggests low pitch; conversely, low top speed and engine overload may indicate a pitch too high.
Use the 15″ pitch to optimize mid-range performance but adjust if needed based on boat load. For vibration, inspect blade symmetry and balance, and consider swapping hubs if slippage occurs. Always consult your engine manual or a marine technician for precise resolution.
Comparing Pitch Options: 15″ vs 17″
Pitch selection should match usage patterns. The 15″ version excels in acceleration and responsiveness with heavy loads, whereas the 17″ pitch favors higher top speed with lighter load conditions. Fishermen who drift or tow gear often opt for 15″, while recreational speed users may exit for 17″. Understanding how to select pitch correctly maximizes each deployment of your Amita 3 propeller marine.

Detailed FAQ Section
Which Volvo Penta engines are compatible with the Amita 3 (15 x 15″) LH Propeller?
The Amita 3 model 8712‑150‑15 is compatible with various Volvo Penta Aquamatic sterndrive engines—commonly 4.3L, 5.0L, and 5.7L models that utilize left-hand rotating propellers. Before purchase, verify your engine’s spline count, shaft diameter, and rotational direction. This ensures proper fit and performance, essential for torque management and thrust balance. For twin‑engine boats, this LH prop pairs well with a right-hand propeller on the opposite side to maintain stability during acceleration and cruising.
Is this propeller suitable for saltwater environments?
Yes. The Amita 3 propeller marine design uses treated aluminum with protective coatings resistant to corrosion. Rinsing with fresh water after each use and applying marine wax seasonally enhances longevity. Many users report multiple seasons of saltwater use with minimal degradation when maintained properly. Avoid prolonged exposure to marine growth or rough surfaces to preserve blade integrity.
How often should I perform maintenance or consider replacing this propeller?
Experts recommend a visual and functional inspection every 20‑30 hours of use or monthly during high season. Check for blade damage, hub condition, and smooth rotation. Replace propellers every two to three seasons in high‑usage or saltwater environments. If you notice reduced fuel efficiency, increased vibration, or difficulty reaching top RPM, an inspection or replacement may be warranted.
Can I install the Amita 3 propeller myself?
Yes. Installing the Amita 3 propeller marine is typically a DIY-friendly task. You’ll need basic tools—a prop wrench and marine grease. Follow safe procedures: shut off the engine, lift the boat, remove old prop, clean shaft, apply grease, align the new prop, torque nut per spec, and secure cotter pin. Double‑check rotation and clearance before launching. The process usually takes 15‑30 minutes for newcomers.
How does the cost and durability of Amita 3 compare to stainless steel options?
Aluminum propellers like the Amita 3 offer excellent affordability, are lighter, and easier to repair compared to stainless steel models. While stainless is more durable under high-speed or very rocky environments, aluminum performs well in most recreational and light commercial marine activities. The 8712‑150‑15 propeller balances cost and durability, giving mariners dependable efficiency and easier replacement in the event of impact damage. Routine maintenance ensures extended service life at a fraction of the price.
