21' Superboat Speed?

I am wondering what I should expect to see for speed out of a 21' Superboat with a 225 promax on it.

mine went a best of 78.5 if i remember correctly. Boat was balanced and easy to drive

Oh wow! That's a lot better than I thought. Looks like I might have to put a promax on mine.

Mine went 88 with 250 efi with 300 ign.

When I had a 250 Eric it went a tad over 84 with no real tweaking or set up. I like the rough water capability of the 2.5 liter

^ I agree 100% on that.

I like the speed of the 300x

My wallet aint big enough for that lol

So, even with a warmed up 2.5 200, or like a 2.5 200 ported to promax, I should notice a pretty big difference to my 2.4 200 I had on it?
