X Star Prop question

O.K. I know nothing about this stuff, but I have asked a general question on what prop to put on an '07 MCX X-Star, and I was curious if there are virtually unlimited options or there are just a few. My boat is coming with a 14.25 x 14.5(or 14.0)...is there really a difference between the two? Does the "cup" make a difference? Thanks for your help!

Yes, cup/size will make a difference. How much ballast are you running?

OJ makes (at least) 2 choices:

#472 14.25 X 14
#473 14.25 X 14.5

I'll be running the 14.25 X 14.5 on my '05 MCX X-star this year. I believe the newer X-star comes stock with a 14.25 X 14. Look at the stamped numbers on your prop when you get it.

I'll post some performance numbers when I get in the water in about 4-5 weeks from now. I'll be running stock ballast plus about 1500 lbs.

(2) 400 lb. sacs in rear lockers
600 lbs. lead under front seats. (approx.)

This is what I'm going to start with, boat still in storage for about 4 more weeks.

Question: should I fill the (2) rear on-board tanks too or leave them empty? MYMC says filling them may make the wake more "rounded" because their location is not that far back.

We now offer another size for the MCX and 6.0 motor, 14.75 X 15.5 LC XMP EDGE 4-Blade part # 522. This propeller has replaced the 14.25 X 14.5 as standard from the factory. We also now offer a 14.75 X 17.5 LC XMP EDGE 4-Blade for the 8.1 set ups. We still have the 14.25 X 14 and 14.25 X 14.5 in production as well.

Interesting information.

So for all 2008 X-star boats with the MCX and 6.0 motors come with the 14.75 X 15.5 LC XMP EDGE 4-Blade part # 522

How is this prop with extra wieght in the boat? Pros or cons in comparision to the 14.25 x 14 prop?

Correct, the 522 is now standard. The addition of extra ballast, depending on how much, may require propping down to the 14.25 X 14.5 or for extreme extra ballast the 14.25 X 14. The 522 runs very well even with some additional ballast.

My plan is to have the fly-high system (2500 lbs) and at most 5-6 people in the boat... would this suffice? I don't necessarily need it to Snap out of the water... I will have the MCX
