I found this post from way back. Should give you a good idea on your top speed. If your a stock 496 mag non-ho you will most likely be shy of 70 but I was wrong above in stating it was under propped. Looks like the 23p prop is what you want, my bad.....

My buddy has a 05 h2x with a 496 mag and dana manifolds with a 26 bravo 1 prop and runs right at 68 mph at around 4900 rpm.

Newspeed- Speed in a boat is like crack... its great then you want more... than you need more......

Just stating my observations....

BTW welcome....

lol!

Its not that funny.

My buddy has a 02-03 h2x with a regular 496 mag. Not a HO. He has Dana exhaust and changed prop, other than that, it's factory. He is somewhere around 73 on gps. It's a nice ride, it handles very well, should be a real nice boat for the family. Congrats

Disregard my last post. Me and cdail are referring to the same boat. Maybe someone has been telling me their boat goes faster than it really does imagine that haha. But it is a nice handling boat.

You certainly keep busy connecting your lips to Andys ( aka Hoodini) A$$!

And so as not to hijack, to the OP, best of luck with the new ride!

Your a real funny one . Haha he is my friend. Sorry it seems to bother you so much.

Frank. Thanks man. Sorry for the hijack.
