i own a 2006 stx 12 f and last year just before i had it winterized it started to bog down, put in dry gas hope it would work seemed to help but this year for the first time i brought it out it still bogs down and its worst before it would come and go. iv taken the fuel filter out and drained it hoping to clear out any watter,also changed some spark plugs still nothing put in fuel injection cleaner nothing. If i replace fuel filter will that help any suggestings would help

 

You wont get all the water out unless you drain the tank and put all fresh back in it. Save the gas for the lawnmower or the SUV, they wont care as much. Also try cleaning out the carbs, if it hasn't been done in a while they are probably gunked up. Let us know how it goes.

My jet ski is fuel injected i dont know if it has carbs if so would carb cleaner work

 

Doh! The filter doesnt filter out water, so changing it wont do much for you. If it is water then drain as much water as you can out then run the rest through as quick as you can. if it doesnt get better you may have to start digging into the ignition system. Good luck!
