    1999 Polaris Genesis carb models - remove driveshaft shroud

    Need some help. Proud 60 year old female with 2 of these wonderful jet skis.

    Need to remove the "plastic" shroud to grease zerks.

    I have the original manual and a Polaris service publication books. My shroud is metal and has two 13mm bolts that I can remove on the same side as battery. however it appears to have more bolts under the exhaust plastic tube. How do I do this?

    Looks like I have a total of 3 zerks to do.

    Any help is appreciated. I have owned since new and one of them is on its third driveshaft.

    1999 Polaris Genesis carb models - remove driveshaft shroud

    The 1999 Genesis is unique in a number of ways. This coupler shroud is one example.

    I have only worked on a couple of these and at the moment I don't recall exactly how that metal cover is installed.

    Perhaps you could post a few clear photos to help us see what the problem is.

    My recollection is that there is one grease fitting on the through-hull seal carrier.

    The PTO drive shaft coupler is a rubber bonded type, correct? (item 1 in diagram)
    Those do not have a grease fitting.

    If your through-hull assembly (item 17 in the diagram) has worn internal bushings (item 16, inside the housing) then it needs to be rebuilt or replaced. Worn bushings will not hold the carrier steady on the driveshaft and will cause excess wear of the rubber seal lips (item 15).

    Driveshafts usually last a really long time, often the life of the machine. Something is wrong if you have already had three drive shafts in one of these Genesis. How are they failing?

    What else can you tell us about the machines? Service history, etc.

    The cover doesen't have to come off, there is an access hole in it over the thru hull grease fitting.

    Grease will not correct for a worn through-hull assembly or other mechanical issues.

    If the engine to jet pump alignment is wrong then the drive shaft can wear. If one or more engine mounts is bad then the driveline will have issues.
