shrinking wear ring

[LBE]

So I have encountered this problem on my B1 (144 pump) and now it's starting on my my little FX1. Anyone have a cure for this? I 'm speaking of corrosion (electrolisis?) building up between the aluminum wear ring housing and the stainless liner. This was the demise of my B1 prop and drive shaft.
Scat wants $260 to re-sleve the liner!! ouch. I have a good wear ring now, but would like to prevent this from happening again. suggestions?

wash your pump out thoroughly!!!

WSM has plastic liners in their replacements units, not as durable...but won't corrode. A few years ago one of the local ski rental place was using a all stainless housing, it was heavy but eliminated the problem completely.

Where do you get a full stainless 144 pump liner
I would love one of those

Would honing every so often have any affect?

The only true fix is to replace it. If its not bad and only has a few high spots, you can grind it...but this is only very temporary and if you need it for 1 weekend. Grinding on the high spots makes it thinner so the swelling happens faster.

I have the plastic WSM in one of my pwc and works fine. Riva sells an all SS units if you find yourself replacing these units often - but I think its only for the 155mm pumps (the best option for a lifetime fix).

BTW: Washing pump out isn't going to help and will this happen eventually if ridden enough times in salt. The thing that really kills it is leaving it on a dock.

the fix is to replace it and seal the ends (where the pump bolts togather) with yamabond just a thin layer to keep water out from the liner

I don't think they swell uninformly all the way around, they develop high spots, so you can't really sand or hone only the high spots.

Not a bad idea about sealing it with yamabond, I'll have to do that next time I have mine out.

New housing for a Blaster is only $160,why would you send it to skat for twice the $.

I think my wear ring is swolen also. When I had my stock prop in there it was fine, but when a buddy let me try out a skat super slim in my boat it made a rubbing sound. Whenever I start it out of the water or the pump unhooks it sounds like the prop is rubbing on the wear ring. It was a saltwater boat, but it is very clean. There really is no corrosion in the pump area.

I've got a new skat swirl on the way so should I replace the wear ring at the same time so I don't ruin the prop? I found a place online that sells them for $129.

Would it hurt to put the new prop in and see if it still makes that sound?
