Toffen..your a crazy bastard....what a ride that will be..one guy to drive and one guy to scream. I recently moved my motors in closer trying to pic up a few MPH. They are Mercury Bridgeports mounted 17 7/8 center to center. about 1-1.5 inches between cowls..they actually rub a little on a full lock turn. I have a 24ft v-hull(Banana Boat Ltd) 7'10" beam.Ive only had it out once ..i had a low water pressure problem but i think it is due to the motors being too high. A guy from around my area who told me to move them in closer has run 17.5 centers without a problem. My boat had 22" centers originally with no problems. Good luck..if you put twin 300's on that hull your my hero!!!
