My son flipped his raptor trying to ski a small body of water. Quad wasn't in the water that long but it did get water in the crankcase and know the clutch won't hold. Flushed the oil 5 or6 times no change. Any possible other routes to explore?

 

Add some deisel fuel to the oil...run the quad for a short time...drain and re-fill with oil

Pull that side cover and clean all the clutch plates...my guess is you have contaminated oil in the side case

 

Thanks Raptorjay I called the dealer and all they will say is bring it in.
