Specifications
The Solas 3313-105-14 Amita 4 Aluminum 4 Blade Prop Rh 10.5″ Dia. x 14″ Pitch x 13 Spline boasts a specific set of characteristics designed for optimal marine propulsion. Its 10.5″ Diameter and 14″ Pitch are crucial metrics dictating how much water the propeller moves and how far it pushes the boat with each revolution. These dimensions are critical for matching your engine’s powerband and your boat’s hull design for efficient operation.
The propeller features a Right Hand Rotation (RH), standard for most gasoline-powered outboard and sterndrive engines. Its construction utilizes a durable aluminum alloy, squeeze-cast for enhanced strength and thinner blade profiles compared to some older manufacturing methods. The 13-tooth spline ensures a secure and proper fitment with the engine’s drive shaft, a universal standard for many engine sizes.
These specifications translate directly into real-world performance. The larger diameter and specific pitch are engineered to maximize thrust, particularly in the lower to mid-range RPMs. The four-blade design contributes to increased surface area and better water adhesion, which is key for quick planing and maintaining speed. The aluminum construction offers a good balance of strength, weight, and cost-effectiveness, making it a practical choice for a wide range of boaters.
Performance & Functionality
The primary job of any propeller is to convert engine power into forward thrust, and this Solas unit excels at its core function. Its most notable strength is its exceptional acceleration, or “hole shot.” The boat gets onto plane significantly faster than with my previous propeller, which is invaluable for watersports or simply getting underway quicker.
The mid-range performance is equally impressive; the boat maintains speed more effortlessly and pulls stronger when throttle is applied. This makes cruising and overtaking other vessels a smoother experience. A potential weakness, common to many aluminum propellers, is their susceptibility to damage from hard impacts, though the squeeze-casting process enhances its inherent toughness.
Considering its price point of $113.99, this propeller not only meets but often exceeds expectations for its category. It delivers tangible performance gains that significantly enhance the boating experience, making it a worthy investment over less capable alternatives.
