Ok, checked all 3 batteries by putting a load on them, all checked good. I took jumper cables and tried to hook to battery then directly to starter but when I tried to hook the ground to motor block it was hot before I even touched the hot cable to anything....never figured that one out. I did have a boat mechanic tell me my ignition switch could cause it too. Getting up early tomorrow to take the boat somewhere to get them to fix it. I'll definatly post what the problem was to help others out, this has been a fight and apparently it's smarter than I am cause it has me stumped.
