Hello Friends,
I have a 1998 nautique with the GT40 it has been running great all summer long. I replaced the battery a couple of weeks ago and it has not run at full power since i.e., it does not seem to plane off as fast as it should and i am only running at about 38 mph at full throttle with just me in the boat (i verified via gps to eliminate a potential speedo issue). Normally at full throttle it is running 45-47mph and takes very little time to get there. I just figured that it was the fuel filter so i replaced it as-well, but still the same issues. Also, only running at a max of 3800 rpms or so. Any thoughts or ideas?
