    Eric,
    I am looking for a new prop and repair of damaged prop. I have a 1991 240 Maristar that Has a WOT 0f 47 mph @ 4600 rpms. The damaged prop has a serial #48-18295-13. It is LH and 1"keyed shaft. Do all shafts taper down to a smaller thread? Mine goes from 1" down to approx. a 13/16" diameter thread. Can you give me a price for a 4 blade replacement and an estimate on repairing damaged one.? Boat is used for skiing and waking and pleasure riding.

    Eric,
    I bought a prop from you late last year, I have a 2001 prostar 209 with the rtp-1 predator motor (310 hp). I have a 13x14 prop on there now, I can only turn 4500 rpms, at 41 mph WOT.
    Seems like I used to be able to turn 5000 rpms at achieve around 45-46 mph WOT. I don't know if it is the alignment holding me back or the prop. In the past I have had the prop reshaped by Conroe Marine, and the pitch may have been different. I have taken my boat back to Houston MC and they say the alignment it good. (hit a submerged log last year and needed new underwater gear, strut, prop, shaft.) The I can not turn 5000 rpms, so this leave me to believe I have 500 rpms left. What are your thoughts on this?

    Eric,
    I am hoping you can help to point me in the right direction on a prop issue.
    I have a 13.7 x 15 LC 4 blade XMP on my 2008 MC PS197 w/powerslot and while pulling someone today at 20mph I hit a submerged piece of wood that was roughly 3" in diameter. As soon as the wood hit my hull I pulled the throttle to neutral but obviously my glide carried me over it. I jumped in the water and ran my hand along every inch of the prop and amazingly there was not a ding on it, nor was there any damage to my rudder or tracking fins. However, when I accelerate, at about 18-20mph, I feel a slight vibration back through the wheel but it seems to go away above or below that speed. When I pulled the boat out of the water I visually inspected everything and again, everything looks new without so much as a scratch.
    So, my question is, could I have bent one of the blades without causing any other visual damage? If so, what do you charge to re-work this prop?
    Any advice you can give would be greatly appreciated.

    Thanks,
    Jeff

    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 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

    Eric,

    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
