Solas Amita 3 Aluminum Propeller 9.9x12 for 25-30 HP (Tohatsu/Mercury Compatible)

The Solas Amita 3 (Part No. 5211-099-12) is a 3-blade aluminum propeller measuring 9.9x12, designed for outboard engines in the 25-30 HP range. It’s developed as a universal solution compatible with multiple makes and models, thanks to its standard 10-spline hub – including Tohatsu, Nissan, Mercury, Mariner, and even select Honda models. With a 12″ pitch, this propeller strikes an excellent balance between quick acceleration and a strong top speed on light to mid-sized boats. The three-blade configuration means less drag, which helps the engine reach higher RPM and can contribute to better fuel economy at cruising speeds. At the same time, Solas’s blade design ensures there’s no significant compromise in grip during takeoff – your boat will still plane confidently and avoid excessive slippage. Usage and Recommendations: This prop is ideal for boats about 3.5–5 meters long (inflatable RIBs, small aluminum skiffs, or fiberglass runabouts) powered by ~25 HP engines (such as Tohatsu 25/30, Mercury 25 SeaPro, Nissan 30, etc.). It is also suitable as an upgrade for certain older Honda models (e.g., BF20/BF25) where a 9.9″ diameter prop is required. The Amita 3 9.9x12 enhances the boat’s tracking and turning response, owing to its precisely balanced blades that reduce vibration. Installation is straightforward – the prop slides onto the splined shaft and reuses the engine’s original shear pin (if applicable), thrust washer and nut. The robust rubber bushing in the hub safeguards your lower unit by cushioning shock loads from any sudden impacts, while also contributing to smoother engine operation.

• Wide compatibility – designed to fit popular 2-stroke and 4-stroke outboards ~25-30 HP (Tohatsu, Mercury, Nissan, Honda, etc.), making it a versatile choice for prop replacement
• Improved acceleration & efficiency – the 12″ pitch provides solid “bite” for takeoff, while the 3-blade design with optimized rake allows the engine to reach its ideal RPM range for an economical cruise
• Ideal for small work and fishing boats – this prop delivers reliable thrust for loaded boats (e.g., two to three people with gear) and stable handling whether you’re trolling slowly or running upriver
• Quick, hassle-free installation – replaces factory propellers without the need for special hub kits; uses your engine’s original hardware (nut, cotter pin, etc.) for secure mounting
• Durability & quality build – the aluminum construction features a corrosion-resistant coating for use in fresh or salt water; Solas’s precision manufacturing ensures minimal vibration and noise during operation
