im getting frustrated , i have a merc70 hp , ser # ob227858, i think its a 89 or 90 model , anyway i cant get the motor to come up ,i think it may be the trim motor , but ive seen a diagram of the trim pressure release and mine doesnt look like that it has a round deal that looks like a stripped nut , how in the world am i suppose to get on this thing with any kind of tool, the hole isnt big enough to even get needle nose pliers on it , anyway i have a picture of it but dont know how to post it here ,, any help would be appreciated...!
