I sent a PM to Eric, please see our discussion below. I will be taking his recommendation this offseason:






The new stock prop is the 14.75 X 15.5. This prop will be good on the low end and provide better top end than the 14.25 X 14.

Thanks,
Eric

Eric,

05 X2 with MCX. We waterski, wakeboard, surf......Stock 13.7 X17 (IIRC) provides good top end, but just a little to be desired out of the hole when weighted down. We also have the wakeboard prop, 14.25 X 14 (IIRC) and my cousins complain that it has TOO much pull out of the hole when water skiing. The boat gets on plane in a heart beat! I give it the ole, give it half throttle, wait a second, then full throttle to stop the complaints. Plus this prop spins more RPM's at waterskiing/higher speeds.

Can you recommend a good in between prop? Decent out of the hole when loaded down wakeboarding, yet spins fewer RPM's and has decent top end speed? Thanks in advance.

I have the 14.25x14.5 OJ on my 05 X2, and absolutely love it. I'm comparing it to a 13.7x17 (had the orig prop, had it re-pitched, then bought a new one), and an acme 14.5x14.25. The repitched 13.7 will be... ok. you won't lose alot off the top end but it'll still be slow out of the hole if you really load it down. After getting the 14.25 it was night and day, I'll throw 800 more lbs than i did with the 13.7 and i'll have to hold back on holeshot (since getting the 14.25 i haven't needed to go WOT, ever). I also have that 14.5 acme, the holeshot is just as amazing, but it spins about 500 rpms more than the acme does at wakeboard speed.

It may be 600, but i bet over the course of a few seasons if you're riding alot like me (150 hrs this year) you'll save at least that much in gas.

darh,
forgot some critical info...
ballast with the 13.7 = 2300lbs
ballast with the 14.25 OJ ~ 3100lbs (only ever run this much once or twice, the wake was RIDICULOUS)
I have the MCX too

I have both the 14 and 13.7 inch props discussed in this thread and depending on where I'm boating will use both throughout the summer. While we're on our small home lake it's the 14. When I go out on Lake Erie or the larger lakes we typically vacation on in Northern Michigan during the summer I usually switch back to the 13.7 for cruising and a bit better top end. 10 - 20 miles with the 14 at a good pace will drain the tank pretty quick. In the longer runs the 13.7 just seems to be more balanced.

How you're using the boat will play the biggest role in which prop makes the most sense for you, and what works well for one person could be terrible for someone else.

If you're just looking for the best acceleration and low speed performance, with no concern for top end, then upgrading ACME's 1285 will give you the best possible performance.

If you want a recommendation based on your individual application (altitude, ballast, usage) just contact us.

SInce you have a low pitch prop already, your only other real option besides the high 17pitch wyou also have is the 15.5. I'm presuming the 14pitch gets you a little over 40mph in your boat, then you'll get about half the benefit of top end and half the benefit out of the hole, maybe more, the 17 pitch OEM is pretty turdly out of the hole.

All I can add is this:

Go directly to the man that knows, Eric Johnson @ http://www.ojprops.com/contact_us or contact him by pm, EJ OJPROP, http://www.mastercraft.com/teamtalk/member.php?u=1537
Be prepared to give him any info he may need like, current prop info off the hub, the current altitude you use the boat at, baseline numbers of the speeds and RPM's for the current prop, boat model and year, engine size, transmission ratio, function (skiing, barefooting, surfing, boarding, tubing, etc.), ballast use, fuel load, gear, nominal # of passengers, etc. He will need it to determine the best prop for your application.

I am trying to understand props... I bought My 06 X2 this winter and I am trying to make sure I have what I need for the summer. The boat came with two props one is 13.7 X 17V and the other is 13.7 X 19.5. We plan on mostly surfing and wake boarding I am not much for just cruising. As far as ballast goes I have ordered the fly high system from wake makers.

Thanks for any input anyone may have!

Your best bet of the 2 with your activities would be to use the 13.7 X 17, contact oj prop or acme prop, they are the professionals.

What engine is in the boat? You will need a prop change from the two you currently have if surfing and boarding is all you are looking to do. Let me know what engine you have and I will make a suggestion.
