    Eric, I have an 03 X-2 with the 310 hp Predator engine, the boat is new to me. It has a OJ 14 20 prop on it. When I bought the prop was just redone it seems to have good all round performance, good hole shot, top speed 42. I am looking for another prop as a spare, or the new one as my main. I didn't see that size on your website. Any help would be greatly appreciated. Thanks Sean

    Eric, I have a 2000 ProStar 190. I am looking for a replacement prop. We wakeboard and ski behind the boat. stock motor. It has the original prop on it which is a 4-blade. Any assistance with type and material would be appreciated.
    Thanks, David

    Eric i have a 89 prostar 190 with stock motor 1:1 trans,i am recreational wakeboarder.i have about 300 pounds af ballast and usualy have 4-5 passengers,the 3 blade prop that came on the boat(not sure what size,wakeboard speed 23mph@2400rpm,the top speed is about 38-40mph)does ok,but i would like to get a 4 blade to hold the wakeboarding speed a little more constant,and maybe get alittle more power out of the hole. I do not ski and cruise at a moderate speed 25-30,so im not concerned at all with top speed, i may do some modest engine upgrades(+50hp) in the near future ,which prop would you recommend for me.Thanks,Jon

    I have a 2003 Mastercraft 230 with 350 MCX upgrade.(no ballasts) I think the stock prop is 14x20 and it took a some minor bottom hits. What would you recommend for a replacement? Also, I've never removed a prop before, but do you need the special tools? Do I have the right numbers on the stock prop...Any help would be great. It's time for a new prop and to rebuild the original OJ.

    My X45 L18 with 14.75x17.5 is at about 3200 rpm at 22mph. I'd like to improve fuel consumption, so assume lowering rpm would be helpful. Wakeboarding is primary usage, and its about 3000rpm for 22mph with no ballast. I've got open tips with silentmaster, and 2009 ECM that more matches this config. Maybe this solved the issues that made 2007 and 2008 not be able to use the prop you developed for the 2006 L18x45? I don't want wakeboard out of hole to suffer, right now the boat does amazing acceleration, but the rpm's and gph seem high.

    It appears you are getting alot of questions about props. Do you have time for another or you trying to get away from it. Thought I would ask before I sent you a question about props. Thanks

    Any recommendations for a spare prop for my 08 X2 MCX that will not break the bank? It has a 14.75 x 15.5.

    Hey Eric...

    I'm curious about this post. One of the posters in that thread brought up ISO certification, says he won't run anything less than ISO class 1. I wasn't aware that inboard tow boat props were ever ISO classified that way. What's your take at OJ?
