you sure its not the gearlever beginning to seize and distorting rather than rotating fully? Classic Mariner/Tohatsu/Mercury/Yamaha 5hp problem...
Secondly try adjusting the actual linkblock in the downrod (behind the plastic round cover halfway down the outboard leg..
Good luck....

Someone will be along shortly with a link to the workshop manual I am sure...
