I know this subject has come up alot, but I need some advice. Looking at changing my prop after damaging it. I'm fairly new to boating, but am looking at a prop more suited for wakeboarding. Don't really know what the size of the prop means in terms if it's bigger it's better.
Any reputable sellers on this site? Any and all advice is welcomed.
Thanks in advance.

Oops, forgot to add details on the boat. It's a 2009 X-2. What kind and size prop comes on the boat?

I don't know a lot about this topic but I know you will need the current size. It is stamped on the Prop Shaft, close to the the locking nut.

I'm running the 14.5 x 14.25 on mine and like it (alot). Some people like to have a little more top end, but I'm OK with a 40mph boat. Running the MCX, it could pull stumps.

The standard prop on Mastercraft boats (right now) is OJ. EJ, of OJ is a TT member.

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, 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.

OJ can help you get your prop sorted. How did you damage your prop?

Make sure you have your shaft tested to see if there is any bend it it. Even a slight bend can wreak havock and other parts of your drivetrain

Nice set-up Justjoe. Besides having more puuling power with that prop you switched to, any other differences you've noticed? I don't use the boat for just one particular activity. Alot of wake boarding and surfing. The occasional pulling of tubes.

That's the prop Eric at OJ reccomended for my boat, high altitude, 06 X2, MCX. Stock is 13.7x17, which is what's on it now and it's a real turd at high altitude. (Just don't have $500 laying around after getting the new boat, or the orig prop would already be a spare!) 36mph top end @4500rpms tops, barely get up to speed with the ballast full pulling a 200 pounder up on a board.
Acme has a couple options as well and based on my Prostar, I'd reccomend them too. New prop was night and day better than the stock 13x13, didn't lose any top end speed (still runs 43-44mph), hole shot and acceleration very noticable and no over rev at low altitude with the 13x11.5 Acme.

Yup.

Had the 13 x ? too. I wear it around my neck on a chain now when I go out to the club. It's good for that.

Hmmm.... smoother? (Probably because it's cleaner: read less abuse) It looks better out of the water because it's BIGGER.

Cold water has been known to cause significant shrinkage.
