Just bought a Polaris 650sl. It runs fine while it's out of the water. Once in the water you can go about 50 yards and it bogs and dies.
Will not restart until it is back on the trailer. Once on the trailer it runs fine.
I have replaced all of the fuel filters.
I'm have the same problem. just replaced my stator and plugs. put it in the water and ran great for about ten mins. it would idle put when I throttled up it fell on its face and would start again until in was on land.
