    Bent / Broken impeller

    Was out today in deep water 30+ ft hit a small wave and the ski would just rev and only go 5 mph a few minutes later heard metal clanking. Towed back in, and saw on of the blades on the impeller was bent back. With pliers and it cam right off, so I could flush out the ski.

    Not sure what that looks like, but did get the impeller off today here are some more pics.
    The wear ring looks good no seperation that I can see from corrosion.
