Stock Prop for 2004 X-Star 8.1L

Does anyone know what the stock prop is for a 2004 X-star 8.1L. Test drove one today that didn't seem to have what the MCX or 6.0 L in the hole shot, It did not have the stock prop on it

I have an 05 x-star and the same issue. I think they come with a 14.5x22 prop stock. Every prop guy I talked to said that was way to much prop so I got a 14.25x20 and it made a big difference.

Thanks Boo, what did your top speed change to when you changed props. This one I test drove was about 41 to 42mph. I did not think to notice what the RPM was but it did sound pretty low and seemed very sluggish compared to the MCX or 6.0. who did you talk to about changing props?

when i changed to the 20 pitch everything improved, my top speed with three people in the boat is 47, rpm is about 4600, and it gets on plane alot faster. I'm not sure why they put the 22 pitch on as stock.
