    Cool another prop question!

    Hi,
    Just seen OSIDEBILL's pdf from Solas in another thread.
    Solas recomends for the gp1200 a 13/19 concord, AND a The X prop profile for the gp.
    Im running a 8 hour old 13/19 concord.
    Is it really worth swapping out for a X0?
    where am I really loosing with the 13/19? Bearing in mind Solas recommend both!
    Iv'e got flame arrestors, pre mix, cooling line teed and a Pro-Tec 150psi rec head on the engine mods.
    I want it right,and will buy a X0, but it's kind of hard to justify a new X0 if the 13/19 does not loose a great deal against it.
    Thanks.

    What speed and rpm are you now.
    You will turn more rpm with the X prop.

    I thought the hub size was the major difference between the two .. that the xo's hub was smaller and was able to pull more water thru the pump..

    Size and shape of hub are different as well as the blades being cut different. The XO's have a straight blade and the Concordes are cut like a Skat-trak swirl. The XO is definitely the way to go for top-end #'s the Concorde will be slightly slower but hook-up much better in chopped up water. This is what I've experienced running them.

    thanks Mike.
    That's exactly what I wanted to hear!
    Most of my riding is in the chop/surf, so i will stick with the 13/19 Solas.
    One of the other gp1200's I ride with damaged a prop a few weeks back, and all he could get hold of in a hurry wasa the Skat swirl 13/19. That prop is VERY good in the rough!

    Scott,
    From what I remember it was .5-1.0mph slower, although in chopped up (racing conditions) or rough water (boat traffic, windy conditions) it is faster than the XO and doesn't cavitate like the XO. My experiences were with the GP800 and the smaller 144mm pump, but I would imagine the larger pumps to be similar. Since I started running Skat-Trak Magnum (D-75 148mm) pumps I've run swirl impellers exclusively.
