I just bought a 1976 Starcraft Holiday boat, test drive went well after the seller "stepped on" the transom so the prop would go down. Some of the lights didn't work so a friend (?) said he would do some some work on it and fix the lights while I went to get a truck, hook the trailer up and pull it out of the lake, my friend (?) said he needed to "fix" a few things and would have it done the next day. after several hours he came up to the boat ramp with the boat and when I noticed I had the key in my pocket I new I was in trouble. The wires around the battery/engine are all messed up, the transom wont go up and just makes a high pitch sound (no fluid?), bilge pumps don't come on, lights don't work, IT'S A MESS! where do I start, can't find a service manual,HELP!!!!!!!!!
