    Unhappy MSX 150 flipped now won't go over 5900rpm (42mph)

    the kids(not mine) flipped it over, story not clear!! may have been running????at worst going 5mph!! may have have rolled it back over the wrong way so they rolled it back over then righted it the correct way to make it OK!! But it seemed to run alright! I didn't ride it, put it on the trailer and went home next time out was vacation(of course) and the older boy took it out and he flipped it turning at slow speed... righted in correct direction. Then a few minutes later while towing a tube 20mph-ish it let out a cloud of smoke. They came to me. It had some water in the hull much more than usual. Oil everywhere. I put it on the trailer went to the car wash then took the hoses, inner cooler and cleaned them as best I could with limited tools I bought at Ace Hardware store at a vacation condo. changed oil, plugs. put in water and seemed fine EXCEPT.. it won't go over 43mph (5900rpm). Took it home and repeated the above more thoroughly. I cleaned the Map, boost and O2 sensor with CRC electronic parts cleaner, blew out the innercooler with a backpac blower and it still won't go over 43mph. NOTE the oil is at least staying clear. I had it out yesterday and did notice a little hunting just off idle but ok after that (and the 43mph top end) I can hear the waste gate blowing off on rapid decel.!! Help headed out next week for vacation and she would like to take them-their her toys
