I'm just playing with this combination but this weekend in moderate chop I saw 83.9 GPS. That was me in the boat, half full of fuel. My boat is also 40% Kevlar layup.

What rpm?

5200-5250 .... that's all she'll spin.

I am running 78.5 @ 4900-5000rpm with stock bravo's and a set of 30's. I need more rpm's but need a cam and carb change on my 540's.

You definitely need something. My old carb'd 500HP boat was running Bravo 30 4 blades at better than 82mph. That was around 5200-5250 rpm as I recall

Damn, I wish my P-38 was a 1999 instead of a 1998. I could probably get 85-87 with my set up with (575 sci- tweeked to 650 hp) in an AVS hull based on what you are getting. As is I struggle to hit 80.

Michael... my boat is also quite a bit lighter being a Kevlar layup. I talked to a man that moved up from a 1996 38 to a 38 AVS, both with 1200s and #6s and he said the non-stepped boat wasn't terribly different at all minus the weight differences.

interesting, I was under the understanding that the avs was about 5-7 mph faster pound for pound. There are not too many comparisons here on oso that people take between the hulls.

Michael.... and who knows with his setup also. Not many of us have 1200s and #6s. My boat is for sale... and extremely reasonably priced if you know of anyone interested. I have my eye on something new and have to let her ride.
