I have a Bayliner with a Force 125hp engine on it. The boat has sat for about 2 years, with occasional starting and it was winterized during this time period.<br /><br />I have rebuild both carbs, putting in all new plugs in the carburetors. I cleaned them very good and made sure that all passages were clear with compressed air. I have put a new Fuel water seperator on the boat. I also put new plugs in the boat. I then removed the old gas and put fresh gas mixed at 50:1 ratio in the boat. I took it to the lake yesterday to run it, it runs perfect on the driveway. When I got on the lake it runs perfect up to about 2000 RPMS, then it bogs down. Its like its starving for gas. So knowing the first thing that I would be asked on here, I squeezed the bulb, its pretty tight, but when the RPMS get closer to the 2000 mark, its not as tight as it should be. It still is tight, but not very hard like when I pump it up.<br /><br />I have replaced the Fuel pump back about 2 years ago, before it sat. I have not checked this yet or the little Screen filter that is mounted on the gas in to the Fuel pump.<br /><br />I also tweaked the Air screws on the carbs while on the lake and got it to run a little better. The Timing was set dead on before, have not had a chance to check this yet, to make sure it has not changed, but it should not as all nuts were still locked in with locktite. The boat also has 2 marine batteries which were both charged up.<br /><br />Does anyone have any ideas as to what could cause this?<br /><br />I ran the boat for about 4 hours at low speeds, and it seemed to run fine, just would not get moving. What it would do is when I gunned it, it would get to about 3000 and just flat die, and if I did not pull back on the throttle it would turn off. Another note is that it only does this when in gear with a load, so it only does it in the water. If I put it in Neutral, I can get the RPMS up to about 4500+, didn't really try it to long, but it revved right up to 4500.<br /><br />Thanks,<br />Bryan
