I am following the instructions on page 379 of Clymer's Rude/Johnson Repair Manual to remove the gearcase on my 1976 115 HP Evinrude, but I can not find the shift rod retaining pin under the carburetors area, as it is depicted on figure 7B. Is it possible that this engine was designed with another way to loosen the shift rod?<br /><br />Thanks in advance
