That is because the propeller operates half in and half out of the water also call surface-piercing propellers, when the prop is powered by an engine, it only spins half in the water that cause less load for the engine and enable engine to deliver more RPM back to prop to make the boat run faster upon the water with less drag. And the best known manufacture for these surface drive units is the Arneson surface drive. Blade-X steerable surface drive was inspired by Arneson Surface Drive, it was designed with Arrow Shark’s forward thinking and creative ideas, and was constructed with various materials and multiple manufacturing technologies to accomplish the every single details to be perfected on Blade-X! The main body of Blade-X and the steering cylinder brackets plus the center trimming cylinder were manufactured by precisely molding technology to produce the unique appearance that couldn’t be done by CNC machining, and rest of the components was completed by CNC machining with various materials such as T6 aluminum, Copper and stainless steel to ensure the rigidity and prevent from rusty for the long-lasting performance. Our exclusive design of steering system allow you to take advantage of flexibility of the flexible shaft as the connection device for the steering control rather than use a universal join. The prop-shaft was made of stainless steel and has a 1/4 inches square insert hole to accept the match size shaft straightly, and it was supported at both end by one stainless steel bearing and one graphite self-lubricating copper bush for the ultimate centralized control, this innovative directly flexible shaft steering control design improves not only the power output control, as well as the less drive maintenance.
