seadoo wake 155 wear ring question

[leo2casper]

how do you know when the wear ring needs to be replace? Little rock got stocked in it.while was in the water, accelerate it , but didn't go. So at home i got the rock out , and it looks that nothing is broken
But the wear ring has some scratches. How do i know if it need to be replace? Thank you

Pull the pump...check clearance between prop and ring. Use spark plug feeler gauges.

.010-.015 acceptable...tighter is better.

You need the shop manual for your ski. The gap between the wear ring and the impeller depends on the pump. For example, Check out this link:

http://www.sea-doo.net/SHOPMANUALS/PWC/2002/2002/smr_V2/V2_2002_sect.12a.pdf

For a GTX DI (page 4), the max gap is .040. For the 4 Tec (page 25), it's .014. Keep in mind this link is for an '02 model, so again, you will need the specific manual for your ski.

If your going to pull it apart to check clearance, have a new one ready. IMO for the work of pulling all apart for suspected ring, 9-10 times you end up changing it out, they are reasonably cheap, not end of world to have it on shelf if u don't need it.
Also if you do change it the freezer trick works great IMO

eh....not for me. With an ss ring...I can pull the pump, check the clearance, grease the cone, re-assemble and re-install in less than an hr. A lil practice is all that's needed.

Just ride it and see if it's fast enough. If it is, keep riding.
