SJ Pump locked up.

The stainless wear ring on my back up boat pump has swolen and froze the impellor. Was working great until it sat for a couple months. Is there a 'Back yard' fix for this? Or should I send it off to have a new liner put in.

You can grind it, but ultimately, get a new wear ring.

 

[norcal ex]

where is the best place to get the plastic wear rings?

 

[Big Kahuna]

any WSM dealer, I can get you one if your interested.

 

[norcal ex]

I actually am... Can you get me a price. The shop I work at is a western power sports dealer and I get everything at cost, Do they have it?

 

[Big Kahuna]

they should be able to.........

 

[superramjet]

to get back on the water cheap I had a machine shop hone one once. they had a large hone for tractor cylinders. a new liner is the way to go but sometimes you just need to get back on the water fast

Mine's just started to get a little tight too, are the plastic aftermarket ones alright or am I better off with oem?

 

[SUPERTUNE]

New oem only from Yamaha! Plastic ones suck, they won't last very long and your back to where you started...

I was under the impression that the plastic ones do not swell.... am i wrong?

 

[Matt_E]

Back to where you started - as in needing a wear ring.

Wow, I have been using a plastic wear ring for the last year, and I have had no problems, and the clearance is still perfect.

:dunno:

 

[Mouthfulloflake]

speaking of, what should the clearance be?

I fear mine is larger than it should be. ( freshwater, no swelling liners to deal with)

Ketsair and I had jokingly talked about brushing epoxy all into the pump to decrease the impeller tip to wear ring gap.

I might try that.

.024 is the limit and don't do that yuck!

Well maybe on Ketsair's pump because it looks like it was sitting on the ocean floor for years.

 

[Mouthfulloflake]

thats what got me to thinking about it. his has MASSIVE clearance, mine is not so bad.

I dont see the harm though, brush it , sand off the HIGH spots, let the impeller self clearance the rest, it probably wont last all season though.

Wouldn't the plastic one's suck for people who beach their ski in the sand often? Seems like the sand would wear down a plastic wear ring compared to a stainless one.
