    Eric, I also need a prop recommendation. I sheered one of the blades cleanly off on my last trip out last season (or else it was already fractured and flew off?). Anyway, I am ready to hit the water except for needing a new prop.
    Boat: 2004 Mastercraft X-9 with Indmar TBI 310hp engine.
    Current prop: 4 Blade 12.5 X 12V TC OJ 17004 (splined)

    Are there other compatible props available that I should consider which would improve my performance?

    I have only had the boat for one season so I don't remember at what RPM's I was mostly operating at. However, my main uses will likely be to pull my 7 yr old son and his friends wakeboarding and tubing and occasionally me (200 lbs) and other adult males on skis or on a wakeboard. We are also going to try wakesurfing this year and may load the ballast tanks for that activity.

    I have found a used 12X13 TC OJ splined prop for sale which appears to be in good shape. Is that prop a viable option for my boat?

    Thanks in advance for any help you can provide. I am anxious to hit the water.

    I was told to contact you for some prop advice. I have a 1989 Prostar 190.

    Here is my post on Team Talk:

    "I recently went to the local prop shop to have my prop repaired and they told me it would take a couple weeks to get it back but that they had a newly refurbed OJ prop that I could get for $250. I bought the prop (13/16P- 4 blade). I got on the lake and when I was comming of the trailer I hit reverse and the boat went forward. Brilliant!! Memorial day weekend and I have the wrong rotation prop. So I used the boat and just drove in reverse, which is forward for the day and when I got home I put my slightly damaged old prop back on. I am hoping this didn't damage my transmission. It seemed to work fine, I just had to pull instead of push to forward throttle.

    So here is my issue. I am not sure if this is the case for all p190's, but mine does not take wakes from on-comming boats very well with the stock prop. It beats the hell out of anyone in the front seat. So I thought a higer pitch would keep the bow in the water better. I also don't want to lose the power out of the hole. I am also not sure if I should have a 3 or 4 blade.

    If anyone has advice on prop selection, I would greatly appreciate it. "

    I don't use any ballast sacks and do have a tower going on next week. I use my boat for wakeboarding and tubing. We also spend a lot of time just cruising and hanging out. We live on Lake Oroville n Northern Cal and it's a pretty big lake with lots of boats on it all the time so we encounter a lot of wakes. Someone recommended a OJ XMP CNC 13 x11.5. Any advice would be greatly appreciated.

    I have a 2007 X-Star with the 8.1L engine. It has the 14.25 x 14 prop on it and I've been seeing a lot of talk about the 14.75 x 15.5 prop for the 8.1L. Can you tell me what differences I'll see and how much the 14.75 x 15.5 is? Thanks.

    Got your email. Thanks for the info. That's what I get for trying to save some money. Who knows, maybe I'll sell it back on ebay and may make a few bucks ;-)

    I have a 2007 Mastercraft X-14 with 310 hp RTP-1 engine. I bent my prop last weekend on a piece of wood debris -- I'm going to have it repaired but I'd also like to buy a new one so I'll have a spare.

    I use the boat about 50% of the time for wakeboarding (~2500 engine rpm), 40% for slalam skiing (~3100 rpm), and just cruising around the remainder (typically 3000-3500 rpm).

    Can you recommend a replacement prop? I don't have any issues I'd like to address (hole shot, top end, etc. are fine), but if there is a prop that could improve fuel economy without a noticeable drop in performance that would be great.

    I'm not sure exactly what prop is on my boat currently. One MC dealer told me it was a 13x11, another told me it was 13x12.

    i have a 2005 x-45 with the lq9 motor i was wondering if you have a prop that might work better with this setup then stock

    top speed is good but i would like a stronger pull out of the hole with out killing the top end speed any props that might do that

    I'm looking for a 13X11 for a high altitude application or to rebuild my 13x13. What should I expect as far as cost for these choices and do you think that amount of change (13x13 to 13x11) would make much difference?

    my buddy hit something in the river yesterday in my boat. I dont know if it is repairable or not. If i Send you a picture can you tell or do I need to send you the prop. It is 13x13LH and I think it is a stainless steel prop

    If you want to call me that would be fine also 419.279.9968 Spencer

    I have a 2003 MC X7 with the original OJ 14x20 prop, the boat has the 310 hp Predator, with a 1.5:1 trans. I use the boat 99% for slalom skiing, the lake I use has a short set up into the course, and at 36mph the boat is up to speed just before the gates. Is there a prop you could recommend for better hole shot so I can get up to speed quicker? Also if it is possible I don't want to be turning tons more RPMs, I'm not worried about top end, but fuel consumption, a little more RPMs would be OK.
