Thought I was doing good. Now I am back where we started. This is how it went today, after a carb rebuild and testing it under load at a local marina. 1982 OMC 2.5 liter (4cyl) OMC sterndrive.<br /><br />On the way to the lake, stopped by Wal-Mart and picked up some gas treatment. Then stopped and put some gas in the boat, along with the treatment. 89 octane. Just a little over 3/4 of a tank full. At the lake, launched the boat. Started it and it idled great. Put in reverse and backed away from the ramp. Put it in forward gear and coasted out of the wake zone. Asked the wife if she was ready and floored it. Perfect, no problems.<br /><br />We had been cruising the lake for almost an hour. At this particular time just a little over half throttle and the boat dies. Started it back up and she pulled out fine. Wide open throttle, died. Like it is not getting any fuel. Now these problems are similar to before, just not as severe, at this time. So, we are riding around a little more and it comes to the point that I think we are going to have to be towed back in. I had to adjust idle screw to keep it idling. And when we were able to pull out, the boat would die when giving it any gas at all. A couple of times she even backfired. After numrerous tries I was finally able to get it going and kept in running by giving it just enough gas to keep it a little over idle speed. Anything more and it would die. Tank is now a little below half.<br /><br />I don't think this is a carb problem now or it would not have run to begin with. I think that it may be water in tank. And it just wont run on water 
. (trying to make the best of a bad situation here) The boat sat for almost a year and had less than half a tank of gas when I got it. Does anyone have any idea of what is going on here? Like I said she run perfect for almost an hour. Then the same problems as before. Could it be starving for fuel? Where is the fuel pump? This may be an unrelated problem, but when all of this happened and when I tried restarting, the drivebelt would squeal like crazy. It does seem kind of loose and not much room for tightening it up.<br /><br />One other thing. When it would die, it would almost not restart. <br /><br />Help please, summer is fading fast.<br /><br />Medic
