stock prop size

[boo4381]

I have a 05 x-star with a 14.5 x 22 prop. Does anyone know if this is the stock prop for boat with the 8.1 Litre 450hp motor? It doesn't seem to pull very well right now. Thanks in advance

Yes, and that doesnt make sense...empty with that prop anywhere near sea-level it should be capable of pulling the handle out of your hands.

MYMC - Do you have a prop suggestion for a loaded X-Star or X-45 with the L18 engine? I am considering going to a 13.7 x 17 or 14.5 x 14.25.

13.7x17.5 is really pretty nice with it... you have tons of bottom and still should be able to run wide open without hitting rev-limit. If you want a little more then do the 13.7x17. I'm not a fan of the 14.5X14.25 on L-18 boats.

Boo, how do you like your x-star with that engine, I am going to be in the market sometime next spring and have test drove an X30 with the MCX and an X45 with the LY6 but I am leaning toward the 450 HP in some used X-stars that I have seen . I have been thru boats that were under powered and don't want to go back there. what is your top speed with that prop? . Also do you have plenty of room in the x-star?

Have you used both props on your boat with the 8 litre? Is yours the 450 HP motor?

I used the 14.5x14.25 on my X-45 last weekend and it was definately too low for the L-18. With full factory ballast and five guys it would jump out of the hole but for wakeboarding the motor was reving 3,800 to 4,500 RPM.

Hopefully my dealer will swap a new 14.5x22 for a 13.7x17 since I have two of the larger props.

I've got an 8.1L X45. After some initial questions, MC shipped a 14.75x17.5 prop. with 2 people and no ballast top speed is about 45mph. With ballast and loaded, you don't know the difference, its great for out of the hole, and we seem to use about 4-5 gals/hr rough estimate. My seadoo (RXT, 200+hp) also uses about 4-5 gals/hr, so I have no complaints about mpg on this 450hp engine either.

MYMC do you have a suggestion for an 2003 x-2 loaded down?
