Well I have had nothing but problems with this sportster, just about ready to sink it. I had a new engine installed, then I had to have the wiring harness replaced, then I had to have a wire fixed on the stator. Now I have a recurring problem. The boat will crank first time just fine, runs fine, shut it down and it might start and it might not. When it does not, it will not even turn over it acts as though the battery is very weak, If I hook a battery to it to jump it off it does the same thing, like I didn't even hook one to it. After letting it sit for about five minutes being connected to the other battery it will turn over, I can then take off the jumper cables and it turns over fine. Problem then is it takes several times of cranking, and I mean probably about 10 to 15 times to ever get it to crank. HELP!
