the thing your impeller is bolted to that whole assembly is your jet pump. if the clearance is to large between the impeller and the wear ring it will cause it to act the way you described. essentially it is like spinning your wheels, you cant transfer the power.

OK, seriously, you have a pump. Its the whole assembly around and including the impellor. If you get something stuck in there, or if the impellor blades or stator veins are damaged it can cause this. Also, if the seal between any of the pump sections is bad this can happen. Its called cavitation, do a search on it and you'll find alot of good info.

If you think your engine is fine, then there has to be something wrong with the pump, or something on the driveline (i.e. stripped driveshaft splines).

#1. Inspect drive line. start by looking at the intake grate and impeller housing.
look for any debris that could be effecting performance. If so remove.
#2. If the problem is not solved above take out pump and inspect drive shaft splines.
remove impeller and inspect stator vanes.
If you get this far I will advise on the removal. its not hard.

^^^Cant have your cake and eat it too. They're either cheap, or easy to install. Unless you want just use some lifter wedges.
