We have a Legend 40 which was purchased at the Annapolis Boat Show in 1990. It came with a KENYON NAVIGATOR 2 speed meter installed. It now appears we need a nylon speed transducer for the same. Anyone know where we might find one? We've called Tidewater, etc. and no one has heard of it. The word "Stowe" is also on display unit. Hope someone can help. Thanks.
