I can only talk from what I have been on but triple 350 CC'S are poker run hanging with the twin 500 boat at cruise Speeds. Of course the blue motor boat can get up to a top speed above the CC but in the end they cruise the same with less effort by the CC even with the 6-8 people on board
Yes if you have a top dog boat like your self then really there is no match or comparison at all.

I know that I don't want trip or quad anything. Don't care if it is a OB or not.
Nate you have a good point but today's closed cooled 500hp I/O's are reliable to.
I am more interested in seeing some 30-35 V hull NON CC sport boats with twin 400's. Like the cats are doing. It would be interesting to see how those would run.

Mine would run 70 with 400s propped conservatively. A lighter 30 step hull would be good for 80 or more.

There probably are a few hours from that like the first time we docked in KW, but I also usually leave one idling while anchored(with the throttle only button engaged so the prop can't spin) as a generator to keep the house battery up. The 300's at idle are .4 gph each. You can't run a generator for that little fuel usage and warranty is unlimited hours(and I don't have a generator).
