Description
The WSM Jet Pump Repair Kit for Yamaha 500 WJ (90) Wave Runner (90-93) Wave Runner LX (91-93) is built for riders who want a tight smooth jet pump again. When pump bearings and seals wear the pump can get noisy develop play and allow water to creep in. A proper rebuild helps restore smooth rotation and stronger hookup so the ski feels consistent off the line and through the midrange.
This kit is ideal during seasonal service or any time the pump is apart for wear ring or impeller work. If you notice cavitation on holeshot vibration at speed or a rough feel when you spin the shaft by hand it is time to refresh the pump.
