    How bad is this corrosion

    Is this something to worry about?

    Can it be cleaned?

    Engine looks clean.

    with some time and effort, yes is the response. Can probably wash most of it off, then take your die grinder with a scrotch bright pad and polish it off.

    Thanks..... I just bought this ski and I was promised it was never in salt.....hmmm. Is this a normal issue from leaving it in the lake or
    a salt issue.

    I would imagine I have to get that off or it will continue to get
    worse.

    As you might be able to tell Im a chiropractor and not much of a mechanic.

    I really appreciate everyone's help. You all are a great community.

    Should I replace the ride plate. Since its corroded I might as well
    get rid of it as well as the stock intake grate.

    It depends on how deep the pits are - can't tell from the photos. I just pulled mine out of the lake after about 4 years. Have you looked at the impeller? If the engine turns over at least the blades haven't grown into the housing (mine was like it had been welded). After I finally got all the pieces pried apart, I found the impeller is so pitted from the corrosion that it goes all the way thru in 2 spots at the trailing edges and about half way thru all over the rest of the blades (so yes, fresh water can do this). I couldn't get the impeller off the shaft, so I'll be replacing both plus the ride plate. Good news is the engine seems fine - does yours run? I took a grinder to the impeller and put it all back together and will put it in the water tomorrow to make sure it's worth spending any more money on ride plate and impeller. Good luck!

    Thanks for the info. I ran it on Friday and she ran like a charm. Mine is not
    deeply pitted at all. Seems mostly superficial.

    I need a gps but my speedo was at 60 and I still had some throttle to go.

    It did idle kind of fast. How fast does the ski move when you are
    off the throttle. I had a hard time docking this ski. Be easier if it wouldn't move at all while idling.

    There's definitely a lot of start and stop buttoning involved in docking. Timing seems to be everything with mine - shut it off at the right time and it spins around to gently bump its side against the dock or even coast in backward; otherwise be prepared to stand up and fend off the nose! Reverse is for cowards.
