    Prop selection for a GTR

    Hi guys, am at that point where I need more prop. Have 4" intake and VTech 8400 tune but am only seeing 8100 rpm with Worx grate. Have yet to do a run with stock grate but would like to go closer to limiter. What prop do you suggest. Can get hold of either a SRZ15/20.5 or 15/21. Would this be to much prop and should I seek a SRZ 14/20.5 instead and pitch to suit?

    Thoughts would be appreciated

    The props you mention are too much prop unless you add more mods to your ski.
    I would ditch the internal IC and get a external one that will add HP. Also your SCer housing is a 137mm back housing and will fit a X impeller and front housing. Seadoo did this to cut cost so it is cheaper for you to mod to a X model SCer. Then I would ask Vtech to get you a tune for a X boat with these parts.
    I then would think you could use a 15-20 de-pitched to a 15-19. Give you some idea. My Stock RXTX with a 15-20 pulls 7880 with a Vtech tune. Add the 4inch air and remove the flame arrester and 8020. SO it needs to be de-pitched.


    EDIT>...... I just saw you had a ET127 in signature. Is it installed? Then I would suggest a Fizzle IC. and for sure a de-pitched 15-20!
