    15/20 or adjust-a thrust

    Hello All
    I have recently fitted an intercooler to my rxp.Before fitting intercooler my ski would just hold 8100rpm on a very cold day.Mods are 14/19 solas , riva grate ,rideplate holes filled, reves bucket cut,R&D extended steering nozzle,worx sponsons,fan in intake duct but only blowing into hull. I have a std air intake on engine.I only got 8100rpm after changing the wear ring and repitching one blade of the prop because it had more pitch than the others. My question is do you think the ski will now have the power to turn the 15/20 even on a hot day or am I better off the the adjust-a thrust and dial it in with this. By the way, this webb site is very helpful and is the only reason that I have got my ski to this point. Prop pitching threads exceptionly helpful.
    Thanks again

    Go with the 15/20. The 15/20 is 1 mph faster than a 14/19 at the same RPM. Lots better acceleration too.

    off topic but do yall see great whites when your riding the australian ocean.

    I'm trying to decide which is the worst place to ski.

    New Orleans = aligators
    Europe or North America = flying 200lb sturgeons
    Australia = Great White Sharks
    Tennesse = flying beer bottles

    You won't know until you try. Chances are you will need to take 2mm out of the trailing edge of the prop.

    Cant say ive seen any GREAT WHITES when riding but funnily enough now you mention it ive had a few mates go missing from time to time.

    Put it this way we strap in good when riding in PERTH Wester Australia as the Great White is just waiting for a sucker to come off his ski.

    Im telling you these BIG BASTA##S dont miss when they want lunch.
