friend of mine had his v out Sat for the first time and the motor first time since my rebuild and it ran great numbers no porpoise at all your motor isn't set right on your transom then it is to deep most likely. his has a 200 evinrude and it ran out with 15 x 17 ss prop 5500 rpm @ 49 mph and 2 adults 3 grade school kids.

Hey Skool, Im so used to running Makos that tend to have some porpoise when trimmed all the way...I cant get my V to porpoise even if I try.....to me I need to get the bow up a little more. I have studied the motor height and had my engine builder look at it also(He races outboards) and it looks perfect. I think next time she is on the trailer I may raise it a notch.....may take an hour or so....just to see what happens

yeah it should um you need a long straight edge to put on the bottom of the hull to the motor then trim the motor as low as it will go and see where your straight edge hits the lower unit. it should be 1 inch above the trim plate on the foot. at the back closest to the transom.

IMO 200 is the perfect HP for most 20' hulls, V20s included...it's amatter of WHICH 200HP you select...so far, I haven;t seen a better match for the V20 than a small-block 200HP Etec...I think Lumberslinger will agree...
If I had to pick 4-stroke power for a V20, right now it'd be a 175 Zuke...and that's only because Honda doesn't make a 175...

I agree with Reel too.
Draglink, I found that to get the bow to fly setback and prop choice tends to help. Trying to be a voice of reason here. I see your V-max and raise you a 300xs. Just not sure how the old girl will react.. Still playing with it.(and the boat too)  BGREEN has created a monster, they were never designed to go real fast. Nobody has come forth to say they found the speed at which the boat becomes unstable/unsafe.BTW- with that crew you had aboard last weekend, it ain't gonna go too fast, nor get the bow to fly without some serious hp. Any captain worth his salt would trade speed for some PYT with glow sticks all day long.

Hum.........for maximum " realistic" speed - meaning engine that's not too heavy........
I'd agree with the small block etec 200 hp....... I'd also suggest an Optimax 225, prop'd and trimmed just right may push a good V 20/21 to 55-60mph light load. That's nice speed because when it's truly flat, you could " cruise" at 40 - 45mph. Nice.
