Re: LOWER UNIT REMOVAL &# EVINRUDE
The '73 motors have hydraulically assisted shifting and do not have the screw mentioned in the above posts, that was for some '77 and later motors. On the starboard side by the shift linkage is a bellcrank fastened by a 5/8" headed bolt. Remove it and separate the halves, which have a pin and a hole on the shift shaft end. Then remove the gearcase.
