So I bought a couple of seadoos 2 yrs. ago. Last summer my mother (crazy) in law wanted me to leave them at the cabin to play on, stupid me I did. The next day they brought them home to me and told me, " I got to the middle of the lake and it flipped over on me, I couldn't get it flipped back over so i told Garrett (my son) to bring a rope and the other ski. I tied it on to the ski and pulled it back UPSIDE DOWN".when I got it back I done the drain technique and got it running and ran it for awhile in my yard. I would let it get hot then shut it down for awhile then do it again till all the water was out. Every since then it hasn't ran like it did. The first few times out it ran just ok. Then a couple of weeks ago it really started bogging down and I heard a back fire. I figured I got some bad gas so I just went out and ran it, didn't do any good. I was working on it today, changing plugs, lubing it and cleaning the flame arrestor on it. After I got done with that I started it up and it was really backfiring and sputtering. It back fired so bad it blew the exhaust apart from the other connection. Please help, I'm really stuck and would like to get them back out on the water. Sorry for the long story. Just thought you would get a laugh out of it or need the whole story for a proper diagnosis? When I start and idle it, it does fine. When I give it gas is when it backfires.
