Solas Amita 3 Aluminum 11.8x10 Propeller for Yamaha/Honda 25-60HP Outboards

The Solas Amita 3 11.8x10 is a high-performance aluminum propeller designed for mid-range Yamaha and Honda outboard engines. With a diameter of ~11.8″ (300 mm) and a 10″ pitch, this prop offers an excellent mix of thrust and speed, allowing the engine to reach the proper RPM even under heavier loads. It’s ideal for engines in the ~25–60 HP range – typically Yamaha F25-F60, two-stroke 40hp/50hp, as well as Honda BF35, BF40, BF50 and other models using the standard 13-spline prop shaft.

The Solas Amita 3 aluminum series is renowned for its quality and efficiency. The blades are produced via a precision squeeze-casting process, resulting in a denser and stronger metal structure. The outcome is a propeller that resists flexing and impacts, ensuring a long service life. The blade design features a slight cup which improves cornering grip and helps prevent ventilation (prop slip) at high speeds. Its black protective coating shields against corrosion in both fresh and saltwater environments.

Benefits of upgrading to the Solas Amita 3 11.8x10: You will notice smoother acceleration and better throttle response, especially if replacing a worn or mis-sized prop. The engine will more easily operate within its optimal RPM range – reducing strain and potentially improving fuel efficiency. The boat’s top speed with this 10″ pitch prop may be slightly lower than with an 11″ or 13″ pitch prop, but in return you gain stronger pulling power and the assurance that your motor isn’t “bogging down” when trying to plane.

Recommended Applications: This prop is an excellent choice for fishing boats, RIBs (rigid inflatables), and small runabouts roughly 14–18 feet in length. With a fully loaded boat (crew and gear), the Solas Amita 3 11.8x10 will provide better handling and acceleration compared to higher-pitch props. It’s particularly well-suited for pulling heavy loads or for boats that struggled to get on plane with their previous prop.

Features & Tips:

• Optimized Pitch for Load: 10″ pitch ensures the engine can reach proper WOT RPM even with heavy loads or in higher elevations, protecting your engine from lugging
• Easy Installation: Direct replacement prop that fits on Yamaha/Honda 13-spline shafts. Uses the existing thrust washer, spacer, and prop nut from your engine (no special hardware needed)
• Versatile Compatibility: Can be used on various outboard brands’ equivalents (e.g. some Mariner/Mercury 30-60hp that have Yamaha-designed gearcases). Always verify spline count and gearcase size for fit
• Maintenance: Rinse with fresh water after use in saltwater to prolong the life of the protective coating. Periodically check for fishing line entanglement around the hub to avoid seal damage
• Upgrade in Performance: Many boaters report improved mid-range handling and planing ability after switching to Solas Amita props – it’s a cost-effective way to enhance your boat’s performance without changing the engine
