Solas Amita 3 Aluminum Propeller 10.1x13 for Mercury/Mariner 9.9-25 HP

The Solas Amita 3 (Part No. 1211-101-13) is specifically designed for lower-horsepower Mercury and Mariner outboards in the 9.9 to 25 HP range. With dimensions of 10.1″ diameter and 13″ pitch, this 3-blade prop gives your boat excellent dynamism – sharp acceleration when you hit the throttle and the ability to achieve a solid top speed under light loads. The blade design features a slight cup and optimal rake, similar to the original Mercury Black Max props, which ensures a steady “bite” in the water and minimal cavitation. What sets the Solas Amita apart is its build quality: the aluminum alloy is pressure-cast for greater strength, and the surface is coated with a durable finish that resists corrosion in both freshwater and marine environments. Usage and Recommendations: This propeller is ideal for small fishing boats, jon boats, and inflatables (about 3–4.5 m in length) powered by Mercury/Mariner 9.9, 15, 20, or 25 HP engines. The Amita 3 10.1x13 helps light boats reach plane quickly, which is especially valuable for lower powered motors. It also contributes to stable handling – the boat tracks well without excessive stern wander, and in turns the prop holds its grip so the boat responds predictably. Installing this prop is very straightforward: it fits the standard 8- or 10-spline prop shaft (depending on specific model/year) on Mercury/Mariner engines in this class, reusing the original thrust washer, nut, and cotter pin for fastening. Note: On certain Mercury 20/25 HP two-stroke models (and equivalent Mariner engines) equipped with “BigFoot” lower units, a different prop diameter might be required – ensure that a 10.1″ diameter is correct for your motor. The integrated rubber hub in the Solas Amita 3 cushions the drivetrain from torsional shocks and reduces clunking noise when shifting gears, improving overall operating comfort and longevity.

• Perfect for small boats – excellent for 3–4.5 m vessels equipped with 9.9-25 HP Mercury/Mariner motors, where quick response and easy handling are desired
• Rapid planing capability – the 13″ pitch and three-blade design allow even 9.9-15 HP setups to achieve the RPM needed for planing, effectively boosting the performance of lower-powered engines
• Stability at speed – the optimized blade profile ensures a smooth ride and maintains good steering control at WOT (wide open throttle) without overloading the engine
• OEM-standard compatibility – the Solas Amita 3 matches the specifications of Mercury’s OEM props (e.g., it can replace Mercury part numbers like 48-19640A40, etc.), ensuring the correct diameter and engine RPM range are maintained
• Reliable value – at a more affordable price point than an OEM Mercury prop, this Solas product offers equal or better performance, a robust construction, and built-in gear protection, ultimately extending the life of your drive system
