Hello all,

Not very mechanical but trying to figure out our 2006 Four Winns Horizon that we trailer. I'm able to start fine, run in idle, go slow speeds to pick everyone up at marina, but when we go full throttle I get no power. You can hear engine going in and out of trying to go fast but just can't. After about 15 mins or so it opens up just fine like it always did. Friend said bad gas so put Seafoam in and changed fuel filter. Also did oil change and new oil filter. Was thinking maybe carb? Any advice would be appreciated. Thank you.
