I would like to mount my Evinrude 50 HP model 50272c to my boat . The boat has the older pulley/rope type steering system . I do not want to change that because I have other vintage motors that I use on this boat. The steering attaches to the older motors via a adapter that mounts to the carrying handle. The 50 HP does not have a carry handle. It has a steering arm just under the motor housing . has any seen a adapter that I could use? thanks
