I have a 97 gtx , upon acceleration it like cavitates out like its not getting enough water in to intake to push out. Any ideas?? engine seems fine just no full power off the line .. Impeller? Dont see anything blocking. How do i get to the impeller to replace repair etc. Thanks Dan W
 
Sounds like you need a new wear ring. Impeller could be dinged up also, if it is you get can get redone for a lot cheaper than a new one. One yours just disconnect ball joint of VTS link rod. Loosen 2 screws each side of trim ring and remove the nozzle. Disconnect steering cable from nozzle before removing venturi. Remove 4 retaining screws and withdraw venturi. Loosen 4 nuts and remove flat washers and lock washers from jet pump housing. Wiggle the jet pump a little as you pull it off.
Check your wear ring clearance with the impeller, clearance should not exceed 1.0 mm. To get the impeller off you will need a special impeller removal tool. They are not expensive and you can order one if you find you need a new wear ring.
