The Solas Amita 3 9.9x11 propeller offers a great blend of acceleration and speed for engines in the ~20-30 HP class. It is made from high-strength aluminum using Solas’ exclusive squeeze-cast process, which results in tougher blades and resistance to wear. This three-blade prop runs smoothly and helps your engine operate more quietly and efficiently, while improving hole-shot acceleration and maintaining a good top-end speed.
The 9.9x11 inch size is specifically tuned for outboards around 25-30 HP (e.g. Yamaha), allowing your boat to plane quickly and sustain cruising speeds with low fuel consumption. It’s well-suited to small and mid-size boats – from larger inflatable RIBs to light fishing craft. The Solas Amita 3 9.9x11 makes an excellent upgrade from a stock propeller, providing better handling and reliability for everyday use.
- Suitable for boats ~3.5–4.5 m in length powered by 25-30 HP outboards (fishing skiffs, small RIBs, jet boats)
- Delivers quick planing and steady handling at cruising speed – especially valuable on moderately loaded vessels
- Recommended as a replacement for the factory prop to improve acceleration, fuel economy, and overall engine performance
With the Solas Amita 3 9.9x11 propeller, your boat gains confident thrust and higher speed, making every outing more enjoyable and efficient.
