Solas Amita 10" x 14" pitch Standard Rotation 3 Blade Aluminum Boat Propeller AMITA3 Traditional Rubber hub Exclusive squeeze cast process Stronger blades with better performance Outstanding acceleration and top speed Our Advantages Reliability and Precision SOLAS uses a state of the art squeeze casting process to make our aluminum propellers stronger and tougher than traditional die cast products. The squeeze cast propeller is almost non-porous, with finer grain size than the die cast propeller. SOLAS aluminum propellers have 4 layers of paint. Using superior coatings and a high-tech painting process ensures excellent anti-corrosion performance. SOLAS aluminum propellers are exposed to over 500 hours of testing in a salt water spray tank. This testing simulates more than 6 months of normal salt water use.
