SOLAS Amita 3 Aluminum 3-Blade Propeller 10.3x12 for Johnson/Evinrude 20-35 HP

SOLAS Amita 3 is a series of aluminum propellers known as an excellent replacement for factory props on small and mid-size outboard engines. The 10.3x12 model provides great thrust and overall performance for Johnson/Evinrude motors in the 20-35 HP range. Built using Solas’ special squeeze-casting process, this propeller features reinforced blades, giving it greater strength compared to typical die-cast aluminum props. It’s also coated with a four-layer anti-corrosion paint, meaning you can confidently use it in both fresh and salt water without worrying about quick rust or degradation.

Thanks to its high-quality construction, the SOLAS Amita 3 10.3x12 achieves improved acceleration from standstill and reliable cruising speed. Its blades are designed to “bite” the water smoothly, minimizing vibration and slip. This means your boat will run more smoothly and your engine can work with less strain, which may even translate to better fuel economy. This prop is especially valuable as an upgrade or spare for your OEM propeller, as it combines an affordable cost with superior quality and performance.

Use Cases & Recommendations:

• Ideal for small fishing boats and inflatables (3–4.5 m) – for example, aluminum skiffs, RIBs, and console dinghies powered by Johnson/Evinrude 20, 25, 30, or 35 HP engines
• All-purpose 12″ pitch – offers a balanced choice for most situations: quick planing even with moderate load, along with decent top speed for getting to the next fishing spot or harbor
• Pitch selection tip: A 12″ pitch is a middle-of-the-road option for this class. If your boat is on the heavier side or often loaded (multiple passengers, gear), you might consider a lower pitch (e.g., 11″) for even easier takeoff. If your boat is lightweight and you aim for maximum speed, a higher pitch (e.g., 13″) would be suitable – just ensure the engine can reach the proper WOT RPM
• Compatibility & fitment: Fits the 14-spline prop shaft used by many Johnson/Evinrude 20-35 HP models (e.g., 2-cyl 25 HP from ’84-’05, 3-cyl 25 HP ’96-’01, 30 HP ’84+ 2-cyl, etc.). It is also applicable to some newer 25 HP E-TEC motors. Installation is straightforward – simply swap out your old prop with this one, no special modifications needed
