Folks I really need some advice here. I was out in the bay today, and the boat ran fine for at least an hour... no problem. Then at about 2700 rpm.. it just stopped and I could not get it started. I thought maybe a battery. So, I ran and bought a new battery and nothing. It seems to want to start, but I can't get it to fire up. Please help? Now it sounds like it want to start, but nothing. Its a 2003 4.3 gl-d
