No Propulsion

[Tom S.]

Hi All, I own a 2002 GTX4Tech. When I go to excelerate, the RPM's are fine but I move a little faster than idle speed. The impeller has some deformation at the lead edge, otherwise all blades are intact. The drive shaft does not seem to be broken. My Service Manual does not show any sheer pin mechanism of any kind.
anyone have any suggestions?
Thanks
Tom

I would be checking the clearance between your impeller and wear ring.

I will certainly try that. But this happened all of a sudden. We were using it one day and the next it started.
I will let you know what happens.
Thanks

6KJR,
Looking from the intake side of the Jet pump, an area from about 5 to 9 o'clock, the gap exceeds the 0.35mm spec. I can actually get a 0.85mm gauge in at about 8 to 9 o'clock. Otherwise there is no other signs of wear.
Do you think that could keep it from exceeding 5 mph?

Thanks

Tom
