Our Propeller Shipping Case Secures Your Gear During Storage and Shipping. Perhaps your propeller ran aground and needs repair or reconditioning. Or you’ve invested in a racing boat and selecting which propeller to use on race day affects whether you win or lose. Whether you own a cruising yacht, a fishing boat, a ski boat or a sleek racing cigarette boat, our new Propeller Shipping Cases help secure your gear during storage or shipping. They are ideal for storing back-up propellers when not in use and when shipping propellers to have them reconditioned. They are available in two models. Our standard model holds larger propellers up to 17" and our large model holds propellers up to 18" in diameter. These rugged cases are constructed using high impact polyethylene. The cases are designed to hold the propellers through the shaft and keep them in a locked position. All cases come standard in black.
