I have 27 hrs. on my ski. Should I change the wear ring? I'll proly have to mid way through the summer anyway, Haven't noticed any cavitation yet but I think its only a matter of a few more hours. Is the SS wear ring worth the $ ?

Probably... I'm sure I'll succumb to that mod before the year is out.

I copied this out the service manual. Maybe it'll help. Check the wear ring around the impeller in several spots. If it's like mine, it will be worn on one side or the other.
Impeller/Wear Ring Clearance
This clearance is critical for jet pump performance.
Clearance can be checked from water inlet opening
or from venturi side. However, the last method
requires more work.
To check clearance from water inlet side, remove
To check clearance from venturi side, remove venturi/
Using a feeler gauge with 30 cm (12 in) blades,
measure clearance between impeller blade tip and
wear ring. Measure each blade at its center. For
GTX 4-TEC clearance should not exceed 0.35 mm
(.014 in). If clearance is greater, disassemble jet
pump and inspect impeller and wear ring. Renew

pull it out and turn it around.... you'll get through the summer nicely.
