    GPR'S 2 inch spaçer or not

    On closecourse raçing at the EUROPEAN CHAMPIONSHIP Rius or even Teddy Pons don't use the 2 inch spaçer.Quicker 0 to 72mph-max top speed gpr's on CC. also the other's gpr's raçer's,prefer better hook up and the boat on the water than top speed, not an issue,they tested,but don't raçe it.
    On endurançe or Offshore raçes we've seen the opposite, have seen the top raçe gpr's with the two inch spaçer.
    From my knowledged the 2 inch spaçer help's to keep the nose down on very rought water condition,jumping wave to wave boat more straight on,not jumping to the sky,and also a good hook up,with the stock yamaha four impellor blade
    Would like to hear more opinions to share information,that's what we all need "Member's of the green hulk 5 star's forum".

    Pretty sure Kerry uses the 2 inch spacer on all the skis he prepares. (which you can assume with his set-up it has a higher top speed)

    Phillip,

    I am pretty sure that alot of the fast guys in the country who had 1200s
    are running the short shaft.

    Is it safe to assume that for smooth water grudge racing, you can get a higher pitched plate on, without the 2" spacer???

    JBracing.
    I've seen exactly the results you speak of. I have one of my skis so that I can swap back and forth. Personally, I like the solid feel of the 2" spacer.

    I'd add that without the 2" spacer, the ski turns harder. I think the added pump length affects sponson placement.
