do you save if you only run one motor at a time? also does anyone else have a problem with gas coming out of the filler neck and vent once you get past a half a tank when filling it at the gas pumps?

I also run 93 all the time due to my superchargers. I am not sure what octane your motors need but if you can run 87 I would. That would save you some money.
WOT all the time gets old to me. It is nice to run with a bunch of boats and cruise at a nice fast speed like 65-75. You can always go WOT to get ahead or just stretch it out everynow and then. My boat tops out at about 86 mph GPS fully fueled and loaded with coolers and 6 people. I thought about putting my smaller pulleys on full time (7-8psi boost vs 3-4 psi I run now) but the ethanol in the gas scares me. Only 1 station near me to get regular gas from and I try and top the boat off with them but on the lake you get what you get.
You have a great boat, it will handle the chop and rough water well. Mine seems to handle the rougher water better at high speeds and better than any other boat I have had. It is like on rails. It will defintely be a night and day difference from the 22 Scarab you have. I used to have a Baja Hammer (same deadrise) and although a fun boat it did not handle the rough water well at all.
The other thing you have to remember is you will need considerably much more hp to get the same speeds that twins will produce. That would pretty much negate any fuel savings you had in mind right there. Not to mention the single will be working harder than the twins as well. I do not think that twins cost 2x as much to run as a comparible single. Depending on how you boat and in my case I would say I use about 1.3 times the amount of fuel as I would if I were to say have a 700-800hp single vs the 2 575-600hp motors I have right now. I am going to look at putting some -2 inch shorties on mine this winter and from what I have heard from others I could expect as much as a 7-9mph gain on the top end due to decreased drag.

not to be a jack but you went from a single 22ft to a 29ft boat with juice up twins and you didn't think fuel was going to cost a lot more? You not only have twice the hp but probably twice the weight.

My 454 Mags have had a little work done on them but nothing wild. We hooked up the computer and it burns 54 gal/hr per SIDE at WOT. Needless to say, that does not happen often and in short bursts.

My twin 502's get around 2 miles per gallon at cruise, running WOT I figure gets less than 2 hours run time on 130 gallons, based on some poker runs.

i would have to agree. I only run one screw and 60 gallons in 3 days is pretty damn easy if you are running hard. IF i backed off and just cruised for three days (which never happens or I would own a 4.3 Mercruiser in a 19 ft Regal) i might be ale to make it 45.
