does anybody know what could be wrong w/ an 1968 85 hp johnson? If you let it run in the bucket it will thru a full tank of gas no problems, but if you get it on the lake, after about 25 or 30 minutes it will shut down and the battery will be dead so you cant get it running again. Supposedly the guy i got it from said he had somebody look at it and he told him the powerpack is out. Now the 2 yellow wires coming from the stator are real brittle and they run to the rectifier. Where those are coming from the rectifier the insulation is all gone & the wires are touching together. Is this why it wont charge the battery???? I bought it for my father in law on an 18 ft glasstron boat and we are trying to get it running good to give it to him for his birthday, any suggestions would really be helpful. Oh yeah the serial# is j2984227 and the moel# is v4al-20a thanks for any & all input!!!!
