Re: 2005 merc outboard
hi mate first check all leads from battery to starter are clean and tight (black and red ones) if seem all good try using another fully charged battery as these 4strokes need a bit of a kick to turn,if no result with other battery remove flywheel cover and see if you can move flywheel back and forhth abit to make sure she is not seized ,make sure the key is off when you do this,try these things first my money is on your connections,let us know how you go cheers dunc333 downunder
