Disappointed, Distraught, & Disgusted With My Ultra 150

If this is your first liner after all these years your doing good. So many or these machines i have pulled these pumps to find what your explaining kawi and yamaha, i dont mess with that seadoo garbage. Just fine a replacement and move on extremely common

Oh, no, not my first. I started looking for a spare or two a couple of years ago when I realized that they were getting scarce and no luck.

Here's a theory to get the sleeve out.

I was thinking epoxy liner too. It's not going to be as durable but you could make a mold and making them would be pretty easy after you get the mold made. A very rough idea would be to remove the liner, fill the cone with foam, get the foam out, then use that as your mold by epoxying over the foam you pulled out.

Epoxy is soft enough to be able to be sanded to fit, you could easily get it close with some 80 grit sandpaper. But it's harder than those plastic liners they were selling. I spent a lot of time working with epoxy because I'm making a js550/760 yamaha conversion ski and reinforced the hull, a lot. It takes forever to cure and it's kind of a pain to work with compared to polyester resin but the end result is a lot stronger.

I drilled out the two 'retaining pins' that secure the liner into the housing. It didn't fall out. I guess I'm going to have to get some steel plate and turn it on the lathe to make it fit, then try to press it out.

I'm thinking about trying to heat the assembly and applying ice to the liner to shrink it. Wish I had more time to work on it...

Actually, I have been working on the 150. My water pipe got a pinhole in it and I brought it home to get it welded. I decided to make a new water manifold, which was last week's project. More about that after I take it for a test drive.

I think galvanic corrosion is holding these liners in. I tried pounding the sleeve out with no luck after freeing the tabs. Its probably going to take a combo of pressure from a press block and simultaneous heat/cold cycles. If the freezer/torch method doesn't work, I was even thinking to embed a coil of copper tube into a concrete heat sink and run water through it while heating the aluminum casting.
