Last night coming off the lake boat wouldn't shift into neutral or reverse. Pulled the cover off the motor and when I move the handle either direction the linkage on the motor doesn't move. Figured it has to be at the controls and the console. Got the handle apart just fine, but is there a tip to accessing the actual control plate that is in the gunnel? Was reading that you have to pull seats and the gas tank cover but didn't know if there were any tips or tricks.
