Solas Amita 3-Blade Johnson/Evinrude 15-35hp Aluminum Propellers use a state-of-the-art squeeze-casting process to make its aluminum propellers stronger and tougher than traditional die-cast props. Squeeze-casting produces propellers with finer grain and much less porosity than die casting and equals thinner yet stronger blades. This provides outstanding acceleration, cruising, and top speed. Superior coatings and a high-tech painting process for corrosion resistance.
