Re: removing lower unit on 90 hp 1981 evinrude
Shift rod under the lower carb area needs to be disconnected.Also insure that you have removed ALL of the bolts from lower unit.If the horzontal joint has already dropped some ,you'll need to install a few of the bolts and draw the lower unit back up into place before disconnecting the shift rod.A sevice manual is highly advisable as a guide and reference tool.
