Shaft & Strut Hardware

Marine struts help to minimize shaft movement and water flow disturbance on your watercraft. Marine propeller shafts transmit the engine's torque to the propeller. Both are crucial components designed for the propellers on recreational and pleasure powerboats. At Discount Inboard Marine, we have a wide selection of propeller strut and shaft hardware for a variety of inboard boat models. We are committed to helping you keep your boat running at its very best, with the very best products on the market. For more information about marine propeller shafts and struts, and to find the right products for your needs, reach out today.
