Okay, i have a 1999 100 Hp 4 stroke that runs fine at high RPMs (once the boat gets to them) But bogs down when accelerated around 2,000 RPMS. if i can get past the bog the boat runs fine. I had the gas tank cleaned and all new fuel lines put in from a former fuel problem, also all carbs have been cleaned. The boat starts and idles perfectly. When i run the engine in the driveway on a water hose the engine does not bog at 2,000 rpms. Only seems to do it when its under a load. Any suggestions?? ANY imput would help!Thanks
