Nexgen is your boat an IO not an inboard, I have never heard numbers anywhere close to yours?

I get a 20-22 knot cruise at 3200-3400 running the same power package. This is with a large T-Top and a good amount of fuel.

thanks for the replys everybody...yes it is 350ci 350HP straight inboard. riprunner whats your fuel burn at that speed ? i fugured it would be a little quicker with this package

[ericminnig]

my boat is an inboard 350ci 350 hp 17" wheel

I was hoping it would be quicker too, it's really the only negative I have with the boat. I started with a 15x17 wheel and based on suggestions here and original specs moved to a 16x17 wheel and a got the same exact numbers with a little bit more vibration. At that speed I burn about 10-10.5 GPH on the smartcraft gauge. My numbers are pretty close to everyone else with inboards that I have talked with even though I push more HP than most. I also have a very tall hard T-Top with enclosure and usually run the boat heavy on fuel so that does effect my numbers slightly.

Nexgen, do you have a t-top, bottom paint etc...? What are you doing to get those fantastic numbers?

[ericminnig]

sorry my prop is 16x19 it a sceptre i get on average 10 gal an hour yes it has bottom paint. thoose numbers are with people and some fuel too.
