I think your calculations are off on the 300x motor. Based on speeds of all the 28's over the years I based it on about 325hp and it comes out to 1.47.
Not sure about a 350hp Opti with out some serious internal work either.
Dale, You are right on the money regarding these big motors. I know first hand as down here in the ocean a good set up with weight moved around is not enough. These 400hp Verados are not for small light weight boats. I know everyone is excited to get more HP but SL brings up a good point.
At the end of the day it all comes to weight vs HP.

Skater Jim brings up a good point and I just cant wrap my head around by having these motors with the extra and weight and ballast needed to offset them that there would be any significant gains.
Unlike the CC that already have had 4 300 verados on the back. Now you are just increasing hp.
Not sure David would like the sound of 4 verados back there. You would lose that lovely sound of 4 2.5's screaming at 8500 rpm!!!
I think time will sort this out and let's see what gains are being had with CC's.
15" mids on them would be nice but in the real world (non lake boating) I would be worried about getting water in the bottom cylinders. This has happened on more than one cc down here.

I agree Ron and Dale. the thing that helped my boat the most was the 15 inch mids and the loss of about 35-40 lbs per side off the transom. the lower center of gravity made handeling so much better that I could carry more speed thru the rough water. Of course I would love more power but alot of races are won just being able to use what you have. the 400's are cool but they have a very high center of gravity being straight 6. 15" mids would help but still going to be tall and the weight is up high. Might put one on a tri toon.

(10). 1600 HP of carbon foot print
The ole 36 is getting ready to have some work done to its bottom soon. Also those bags of sand that we put in at Loto should be be long gone real soon I hope. Getting rid of all of that extra weight, and raising engine height plus bottom mods should clear things up as far as dialing in with the engine combination that ive got now. This will have alot to do with future plans
