I have been working on a project over winter.... http://www.nzjetboating.com/yabbse/i...?topic=26442.0

my question is i seem to be down to 7300rpm. rpm has been slowly dropping since i owned the ski. i haven't looked at anything yet and i will be doing some reading tonight to see what i find. If any one has any suggestions of where to start that would be great.

the motor and pump were from an 04 rxp. roughly 30-40 hours on a complete rebuild.
