I have a chance to buy a boat with a 60hp johnson outboard for a realy good price and the engine is in very good shape. It has steering and throttle controls. I want the engine for my 18' lund alaskan, but I want a tiller handle. The old fella that is selling the boat is not sure of the year of the outfit but the last 4 didgits of the serial number are .....1996. Does this mean it is a 1996? Can this motor be converted to a tiller handle?
