I have a '09 Kawasaki, 4 cyinder. Last week, I put it in the water it ran fine all seemed well. Only ran it in the water a few minutes.
Yesterday, I went to take it out for a spin. First, it started to stall and the electronics went crazy. I got it back tot he dock and the battery wasn't tight, so fixed that. Checked the oil - good too.
Went back out started up and sounded good. Started to excel and it seemed not to have too much power. When it came down to idle there was a banging/knocking noise and a vibration to match. When you excel a couple of hundred rpms, the banging/knocking goes away.
I took it for a quick ride, tried to get it to top speed with me on it, but only could get less then 10 mph lower....
what ya think, pull it out and bringing it in ? I dont think I sucked a rock or anything like that. I did have to replace the impeller last year, because some one beached it while it was running
