Any of the "big twin" tiller handles will work, from about 1955 on up to about the late 1970s (25-40hp). Tillers will have only one mounting bolt. Smaller motor tiller handles will have two mounting nubs and will not work. Make sure you get the throttle shaft & gear that goes on the motor side, too, as well as the mounting bolt, which is a special shoulder bolt with a large cupped star washer.
