    Remove boot and through hull bearing (Genesis)?

    It spins but it won't pull off. Any tricks to make it comply?

    Is the black plastic hull fitting rotating, the rubber hose, or the through-hull assembly?

    If the black plastic hull fitting is turning, you can simply unscrew it. Under the hull is a U shaped 'nut' that mates with the fitting threads. There should be a fat o-ring under the rim of the fitting that seals to the hull.

    Rubber hose rotates freely on the hull side, but I can't get it to pull off the black plastic fitting.

    Does it need to come out?

    If the rubber hose section is not damaged, you can leave it in the hull. Snug down the rear hose clamp, then pry the through-hull out of the front end of that stubby hose.

    If you are going to be rebuilding it anyways, stick a big screwdriver into the through-hull and pry it out. There is an internal gap between the bushings right where the grease Zerk is, a useful spot where a flat blade can lever against.

    Or just find something to pry up from below, against the hull.

    Or snug down the rear gear clamp and unscrew the whole thing from the hull.

    The only part that's "loose" is the rubber hose to plastic fitting. Its very stuck on the bearing side, and I would rather not disturb the plastic side where it screws into the hull. I hate applying significant force to anything made of plastic, but I will continue to work on this and try to get it apart without damaging anything.

    You can retighten the rear hose clamp, then use a big pipe wrench to torque the plastic fitting loose by gripping the rubber hose. It only needs a 1/4 turn or so (regular lefty loosely thread) and then it should undo easily.

    Easier to work on the stuck thing once the assembly is out of the hull.

    I got it off, using a plastic pry tool. There's a groove where the plastic fitting sits, that's why it was stuck. I'm guessing the spring for the seal hanging out isn't good? Lol. What's a good way to determine wear on the bushings? I don't notice any radial play if I pull on it uniformly, but I can rock it slightly on the driveshaft by pushing one end and pulling the other.

    Many of your links need updating in the section "Polaris PWC through-hull drive shaft seals" (Towards the bottom of that section). Where can bushings be found, and how are they replaced?

    I used a WSM aftermarket through hull bearing/seal. IIRC it was about $40 or so and works great. The only catch is there is no place for the plastic driveshaft cover to attach to it. Aside from that, it has a grease zerk, and fits perfectly. I'd buy it again if I'm working another Virage/Genesis.

    EDIT- It says it doesn't fit the genesis models. Not sure why, AFAIK the through hull is the same between Genesis and Virage.
