Michigan Canal Line propellers are custom designed for the Inland Waterway sector, it is the only propeller specifically manufactured to meet the demands and harsh conditions of the Inland Waterway market. Collision with submerged objects and debris, in-experienced boaters and poor propeller materials and design have all combined to create problems for owners and operators on our Inland Waterways.
