The V 20 hits 50mph tops, but any faster ?

I hear you. I have seen a major increase in speed before with a engine swap similar to the one I have done here. But the hulls were different.
The 250 EFI has a lot more torque than the old 2.4. I suspect that you, of all people, know about torque.. The fuel burn on the EFI is 30 or 32GPH. ONE hour of WOT and turn back to the marina... LOL
Just for kicks and since this ain't going as well as planned I will kick you in for mid-30's and also 53MPH. If you win you have to take me to dinner with the Gift Card..

Folks it ain't going to cost you nothin to reply. I am kicking in the dough and a gift card or whatever.

MJ -- Bad idea?
