Solas Amita 3 Aluminum Prop 11x9 for Mercury 9.9-25 HP

The Solas Amita 3 11x9 is a high-quality aluminum propeller designed for Mercury and Mariner outboard engines in the 9.9 to 25 HP range. With its dimensions of 11″ diameter and 9″ pitch, this propeller represents a versatile solution for many small and mid-sized boats, providing an excellent balance between acceleration and top speed. If you’re looking for a prop that gives your boat snappy takeoff performance without overly limiting straight-line speed, the Solas 11x9 is an ideal candidate.

The 11-inch diameter offers plenty of blade surface area, allowing the engine to push water effectively and generate strong thrust when accelerating or carrying a load. At the same time, the 9-inch pitch is moderate – it lets the engine rev up quickly, yet still maintains a good pace at wide-open throttle. For many boats in this class (fishing skiffs, small open motorboats, or inflatable RIBs), a 9″ pitch is considered a well-rounded setup that performs well in varied situations – from solo outings with a light boat to ferrying a few passengers and gear.

The Solas Amita 3 11x9 prop features a 10-spline hub, which is used by most Mercury/Mariner engines in the 9.9-25 HP bracket. This ensures a hassle-free installation – the prop slides right onto the shaft, lining up perfectly with the gearcase splines. The manufacturing is precise: the three blades are factory-balanced to minimize vibrations and ensure smooth engine operation even at higher RPMs. Like other Solas props, this one has an integrated rubber hub bushing to absorb shocks, extending the life of the drivetrain. The propeller’s coating is very durable – it’s resistant to scratches and corrosion, which means it will retain its performance and appearance after long-term use. You can confidently use your boat in both freshwater (lakes, rivers) and saltwater environments, as the protective layer guards the aluminum against oxidation.

Swapping your OEM prop for the Solas Amita 3 11x9 can noticeably improve your boat’s behavior. You’ll experience a more lively response when you hit the throttle – the boat will gain speed more quickly, which is beneficial for maneuvering or climbing onto plane. Also, if previously your engine was running at very high RPM due to a lower-pitch prop, this prop will slightly reduce the revs at cruising speeds, potentially leading to a quieter operation and better fuel economy. In summary, the Solas Amita 3 11x9 delivers reliable, well-balanced performance and is a long-lasting investment for any Mercury 9.9-25 HP owner who wants to get the most out of their outboard.

Recommended Uses and Applications:

• Suitable for small to mid-size boats (approximately 12 – 16 ft long) with 9.9-25 HP engines where well-rounded performance is desired – quick takeoff and decent top speed (e.g., aluminum fishing boats, small console runabouts)
• Recommended for 4-stroke Mercury engines like the 9.9-15 HP BigFoot models or standard 18-25 HP outboards that benefit from a larger prop to push water more efficiently – the 11x9 will better utilize the motor’s torque
• Excellent for jon boats and RIB inflatables used for light water sports (e.g., towing a small tube or child’s water toy) – the prop provides extra oomph at launch to pull the toy out of the water
• A smart choice as a backup propeller – the all-around nature of the 11x9 means it can serve as a spare for various scenarios, giving you peace of mind during boating trips
