I just acquired a 1999 Ultra 150 with 81 hours on it. I am doing maintenance on the ski and plan on getting the seals replace. I seen Group K has a service for the shimming. Any opinion from anyone on the work?

How about replacing the seals on the pump, anyone recall if they had that service and price?

I done seals replacement of my SeaDoo and 750 Zxi before with ease. I haven't found any guides on the Ultra 150 pump seals. I am figuring it must be a sea monster to work with.
