I recently purchased a used 1996 Kawasaki XI SS waverunner. It ran great initally in the water but after 15 minutes it started to lose power. It would never die out. If I waited a bit in idle, it would come back for a minute then do the same thing again. I checked the compression on the two cylinders and it was 130 and 132 psi respectively If I let it sit overnight, it would do it again, run great for a while, then go into the power loss mode. Any suggestions?
