    GP1200R "whine"

    Hey guys, I took my ski out for the first time a couple of days ago. Everything was great, pretty much started right up, ran 70xx rpms...but I noticed a weird noise. All throughout the rpm's there was sort of a low turbo whine that would get louder as the rpm's increased...thats the best way that I can describe the noise. Has anyone ever had this noise? The Air was about 60, the water was probably low 40's, I dunno maybe the cold water running through made the noise? Thanks for any help

    Check pump bearings or a swollen pump liner.

    You have to pull the pump out and spin the drive shaft and feel if the bearings feel rough, And on the pump liner look to see if you have burned purple spots on the liner and rub your finger over them you will feel a bump on the spot.

    Well I finally had a chance to get digging and I got the pump out, and spun the prop and it seems rough? I guess I don't really know how smooth its supposed to feel, but it wasn't smooth I guess...and I looked for purple spots but didn't see any, I think I'm looking in the right spot

    Also, is it ok to use it tomorrow or would that be a bad idea...

    Got the nose cone off now too, and as I take it off water starts gushing out from it, I know this is bad. I guess my next step is trying to figure out how its getting there? Did this do any serious damage? Like am I looking at needing a new shaft? or new pump?

    the pump bearings and seals need to be changed that's were your whine is coming from.
