Re: need help tilt problem evinrude 1979
look on the starboard (right) transom bracket toward the bottom.........
there should be an access hole with a flat head screw and a snap ring inside.
stand clear of the eng when you turn this screw as the eng may drop fast.
only turn the screw out around 1 to 1.5 turns or so............... you dont want to damage the threads on the snap ring...and no reason to remove the screw only loosen it.
if you need help on how to remove the tilt/trim unit just ask there are lots of knowledgeable people on here.
but before you go to those extremes you can check the connections for corrosion and make sure the batt is fully charged.
also if you have multiple switches unhook one at a time to see if one is causing a short.
does the motor make any sounds at all?........clicking from the bilge area or anything?
