Well yet another "Newbie" to the whole jet boat thing ....Got a 18' '71 Eliminator with a Jacuzzi WJ with what i believe to be a B impeller unless it has been replaced some where down the road. Searched around the forums for WJ rebuild info, but nothing found. Does anyone here know what it takes to get to the wear ring to check the gap between it and the impeller??? And what tools i may need?? Or what the clearance is supposed to be??? I have no idea when this jet was last touched nor do I have any experience in a boat with a fresh jet to compare...:cry:
