99' Ultra 150 8 mph max
I have a 1999 Ultra 150. I just pulled the pump, checked the clearance and bearings for damage and found none. The damper spilt so I ordered a new part from Kawasaki and replaced it. I reassembled and reinstalled. I took it out to the lake today to ride and my problem is that it idles great BUT when I accelerate to try to plane it won't. The ski will stay moving all the way up to 4000 rpms and then the rpms shoot up to 6000+ rpms and it feels as if the ski stalls out. It goes a max of 8mph and it will not plane.
This happens when cold or warm, no warning lights and the engine sounds and feels normal. This is the first time I have tried with this ski in this season. Last time I used the ski it ran like a champ.
Now here is the kicker. If I put the trim all the way down, this problem does not exist and it hooks up, shoots out and off I go.
This only happens when THE TRIM IS ALL THE WAY UP! Im puzzled as I have never ran into this problem and I cannot seem to find anyone with the same.
Thanks for your help!

sounds like something in the pump like a birds nest?
