Solas Amita 3-Blade Johnson/Evinrude BRP OMC 90-300hp Aluminum Propeller utilizes a state-of-the-art squeeze-casting process for stronger, tougher aluminum propellers than traditional die-cast propellers. Squeeze-casting produces finer-grain propellers and much less porosity than die-casting, for thinner yet stronger blades. This provides outstanding acceleration, cruising, and top-end speed. Superior coatings and a high-tech, 4-layer painting process ensures anti-corrosion performance. Traditional pressed-in rubber hub absorbs vibration and reduce slipping. Right rotation.
