RC D, that is a neat solution to the problem. Tom, as Dave said I ran a home made tiller conversion for years on my 28 Evinrude Special and never once felt that it wasn't a good solution. And as an added bonus, you can make it from all hardware store items. First off you need a single large strap hinge. The kind you might see on Barn doors. The short side will have 3 holes side by side while the long side will have 3 or 4 holes over a 8 or 10" length. On most (if not all) remote steering motors, there are 2 holes on the front handle shaped piece of motor. Lay the short end of the strap hinge over the holes till one lines up. As luck would have it the other hole won't be far off. Then mark where the second hole goes, and drill it. If memory serves, the handle on the motor was drilled and tapped for either 1/4" or 5/16" fine thread holes. Bolt the strap hinge down to those holes. Then get yourself a nice piece of white oak, about 3/4" thick, 2" wide x however long you want the tiller arm to be. Using the holes in the long end of the hinge as a template, drill holes for the screws that will connect the oak and the hinge. Lastly, get yourself one of those bungee cords with platic hooks on each each. Wrap one end around the tiller arm and hook the other end in the hand hold in the back of the motor cowling. That way the tiller will always retract when you let go of it. You won't ever trip on it that way. If I were to guess at the total cost, I'd guess less than $10 bucks.
I used mine that way for years till I bought the ETEC I now have. Were I ever to need to do a conversion again, I'd do it in a minute.
I actually made up 2 different length arms. I'd use the short one during hunting season when space in the boat was at a premium, and the long one in the summer when I wanted to shift my weight forward some.
