ihave (i think) a 1984 omc sea drive outboard 1.6l model 2baxcr ser. j809725 motor that is having fuel probs i want to rebuild carbs and fuel pump and replace fuel lines but i cant find a service repair manual for it. every time i look for omc manuals all i see is sterndrive stuff. does this motor cross reference to a johnson or evinrude #? i am getting more frustrated looking for parts than i will putting them in!
