The Alpha 4 aluminum propeller provides four-blade performance and acceleration at an affordable price. The Alpha 4 is an outstanding propeller for stern drive-powered runabouts, as well as cruisers. With an Alpha 4, your boat will get on plane quicker and stay on plane at lower speeds than with a comparable three-blade propeller. The Alpha 4 is also an excellent water sports prop.
