Solas Amita 3 Aluminum Prop 9.25x7 for Mercury 6-15 HP

The Solas Amita 3 9.25x7 is an aluminum propeller compatible with small Mercury and Mariner outboards from 6 to 15 horsepower. This prop is specifically designed for applications that require maximum thrust at low speeds – for example, heavily loaded small boats, tenders, inflatable dinghies, or as an auxiliary drive for sailboats. With Solas part number 1111-093-07, it corresponds to Mercury’s OEM prop specifications (e.g., Mercury part 48-828150A12) and utilizes a standard 8-spline hub, ensuring an easy and secure fit on Mercury 6, 8, 9.9, and 15 HP engine shafts.

Featuring a 9.25" diameter and a very low 7" pitch, this 3-blade propeller allows a small engine to reach higher RPM quickly, even under significant load. The immediate benefit is more energetic takeoff and the ability for the boat to start moving without bogging down – critical when carrying heavy gear or when trying to get a small boat on plane. In practice, switching to a 7″ pitch prop can transform the performance of a heavier small boat powered by, say, a 9.9 or 15 HP motor, giving it “more muscle” in the low RPM range. The trade-off is a lower top speed compared to props with higher pitch (such as 9" or 10"), but in return you gain much stronger acceleration and better handling at slow speeds.

The build quality of the Solas Amita 3 9.25x7 is excellent – it’s made from a strong aluminum alloy, cast with precision for optimal balance. A rubber hub bushing is integrated to help absorb engine vibration and protect the gearbox from shock during shifting. The prop comes with a durable factory-applied anti-corrosion coating that stands up to saltwater use, ensuring a long service life. This is especially important for small outboards often used on the ocean or kept as auxiliary motors – the Solas prop won’t succumb to rust or electrolysis even with extended periods in the water.

Installation of this propeller is very straightforward. Simply remove your old prop, check the spline and washers, and slide on the Solas Amita 3 9.25x7 in its place, using the same prop nut and cotter pin. The dimensions and fit match the original Mercury prop, so no modifications are needed. Once installed, you’ll notice that your small engine can push the boat under load much more easily without losing RPM. Low-speed maneuvering becomes more confident, and the engine feels less strained because it can reach its optimal rev range.

Recommended Uses and Applications:

• Ideal for small inflatables, fishing skiffs, or jon boats around 8 – 14 ft in length that carry multiple people or gear – the 7" pitch helps a 6-15 HP motor accelerate briskly even when weighed down
• Recommended for auxiliary outboard motors on sailboats and pontoon dinghies where maximum thrust is needed for harbor maneuvering or pushing against currents – this prop provides better control at idle and low speeds
• Suitable when a standard prop (with a higher pitch, e.g., 9") doesn’t allow the engine to reach the required RPM – switching to a 7" pitch will let the engine rev freely and improve acceleration, protecting the motor from lugging
• Excellent to keep as a spare propeller for small Mercury/Mariner engines – it’s lightweight and compact, easy to stow on board for emergency replacement, giving you peace of mind on long trips
