Pulsareproud, here is what he said. The 1st part was probably my mistake in the 1st e-mail.

I thought they only made a 200xs? I know the have a consumer 250 xb anyway what is the W.O.T of this motor? I found my pulsar ran best propshaft about an 1" believe the pad 10" setback and it could have used more likely 15" to be able to run without positive trim. I don't think the et is the best prop for him because they are designed for light weight hulls although I never tried one on mine. The best prop for all around performance I found was the 27p Merc tempest which I still have.

Many thanks for your reply, the 250xs is new for 2003 through high performance dealers only. Maxiumum rmps is about 5800-5900. Mercury intended for it to run 6300 but cut the rev-limiter back and put a 2 year warranty on it. I will take your advice and try the 27" Tempest this week. What of the three vent hole sizes did you run? The prop comes standard with the medium vent, it has a smaller and a larger available. Did you experiment with these? I'm running a stock 5.5" setback manual jackplate. Not sure where to run prop shaft to pad, any ideas? I do have a pressure gauge, and at wide open throttle Mercury recommends a minimum of 15 pounds.
 
Not sure where to start, but I'll bet it will be a good time.
Good luck in testing, be sure to give us numbers.
