I recently upgraded from a 1978 Evinrude 9.9 with a single lever remote control to a 1989 Johnson 9.9. The gear shift cable connects the same as the older motor but there is not enough room for the throttle connector to go through and connect to the throttle stub because the cable connection from the tiller handle blocks it. Is there a different cable end for 1989 or does the tiller cable have to be disconnected?
