    Lightbulb Blueprinting Pump...

    Hey Boys..

    Any advise on what i should or Shouldn't do when blueprinting my 98 GP and 05 GPr pumps..

    I figured since both pumps will be out for new props i'd spend a few hours cleaning them up..??

    Any before and after pictures would really help here..

    What you got for me Guys..???

    Gerry

    my pump has been blueprinted.

    all the vanes were sharpened, allot of material has been removed from them (they are far more agressive, i would also say they have a different angle on them).

    the hub area has been polished and further material has been removed.

    the 3 lugs where the tail cone attaches has been ground so it fits perfectly flush with the tailcone.

    the entire unit is polished and there are no signs of casting marks or any other imperfections.

    Hello Gerry, Blue printing the pump helps on hook up and cavitation but does not do anything for top end.

    or better put, top end speed in ROUGH water would be increased, smooth water "top end" speed may or may not increase-- of course both situations may require impeller tweeking to achieve the desired results.

    Ive personally blueprinted hundreds of pumps, and anyone whos seen one can testify to the jewelry like blueprint job--- avg time to do a pump is about 5 hours--- and thats knowing what your doing--- if you think taking a dremel to the pump is going to do the job, you may want to reconcider doing the job.

    if your going to tackle the job, patients, a steady hand, and lots of sanding rolls----good luck

    Smile Pump.... getting somewhere now..

    Many Thanks

    To Carl, Jim,Woody(kevin?) and the Spaceman..(dude whats your name)?

    I didn't think i'd make this happen in an hour or so but since i have the GP pump,
    Lying around (waiting on a Prop..!! ) i thought why not give it some attention..!!

    What would really help here is some pictures of a before and after job..

    I feel this work would really benefit the GP in particular since thats my surf riding ski..

    It'll be nice if it make's 60+, but i'm after the holeshot for takeoff/wavejumping..!!

    Again thanks for the input guys...
    Gerry

    PS... pictures really would be a great help..

    Im not a yami guy (Carver keeps tryin to convert me) but here is a link to my pump pics. This was on a ultra 150, the pumps are different but the same principles would apply. You can also check the ultra mods thread in my sig post #17 for a little more explanation.

    Smooth out the flow. DO not sharpen the leading edge of the veins, but sharpen the trailing edge. Think aeroplane wing. Both my yammi's have the pumps blueprinted, and while it can't hurt, It made no real difference to me.
