Need help, am thinking of selling my 2008 C180 SE 215 hp because of this. When trying to pull a skier, I try to throttle enough and it seems to overrev and go nowhere and otherwise just doesn't have the power to pull out of the water. Even with a tube and 3 kids, there just doesn't seem to be the power and over-revving does occur unless I throttle back and take it slower. Just to clarify, I am not trying to go full throttle right away but after takeoff. I love this boat, it is comfy and roomy but need more pulling power. Is there something I can check or an after-market part that can remedy this problem? Please help!
