I bought a 1986 mercury 45 hp and it will run good when you first start out and on top end does good but when you start to troll the carbs will load up and choke down and then its hard to crank back up hard to start off without going dead. I have cleaned carbs and put new needle in but not the seat and i didnt chang floats. I have adjusted the carbs every way you can and just when it looks like its running good , it will mess up again it has 140 psi on the top 3 plugs but the bottom plug has 130 haS NEW STATOR NEW TRIGGER NEW POWER PACT. RUNS GOOD IN yard , but when you put it in the water it starts messing up again. anyone got any suggestions?
