    driveshaft wear?

    I decided to pull off the pump and inspect it because she feels like she was cavitating. When I pulled off the pump I noticed these small gouges on the shaft. Is this shaft toast? What could have caused this?

    WHERE on the shaft is that?

    One thing that was noticed some time ago, is that the stock rubber hose inside the ski, tends to suck inwards under 30mph, and can touch the ds.

    I've seen those marks from a prop nose cone spin and gouge the shaft.

    Also seen those marks when the O-rings are missing inside the intermeddiate shaft....

    so that is why I was asking WHERE on the shaft is that.

    They are about 9" up from the impellar. How could I inspect to see if O-rings are missing? All I did was remove the shaft & pump housing, I didn't see anything else come out either time I've done this?

    Do I need more grease on that bearing inside the hull? I usually fill the line every three months or so.

    Sounds like the stock hose collapsing. Replace it with a gates hose, and call it a day.

    you can see the two small orings inside the I-shaft, if you use a flashlight and look up inside there.

    Like I said. I don't think you have any big issues there.

    Gates hose? Are you referring to stock hose from the zerk fitting (sp) to the bearing assembly?

    On my 99 XL 1200 in the rear compartment there is a "hose" where the drive shaft cuts through the bottom... this is the hose he is referring to.. i believe...

    Yup. From the feedthru on the stringer wall to the hull feedthru.

    See if those marks line up there.

    Otherwise see if they line up with the I-shaft orings.
