Initially this ski was just replace impeller as impeller was damaged and too much gap.
Disconected pump assy. 
Water was sitting inside of bearing room as needs replace bearings and seals.
Impeller was bent and worn too much. Most case it can repair but this customer want to replace to SOLAS impeller.
Unfortunately impeller housing was damaged and won't fit brand new impeller. 
So in the end replace all parts of jet pump unit except impeller shaft.
Brand new! looks good.
