when I drove trucks OTR, I ran into a guy on the Coast of South Carolina. He owned one of those boats and informed me that a weekend on the water would cost about $1500. He said he would run at WOT for 10-15 miles and burn 30 gallons of 93 octane. He was running twin chevy 502's with dual quad holley 750 double pumpin' mechanical secondary, high rise, high dollar... That's 3,000cfm Now we're talkin' gallon per mile as opposed to mile per gallon!
LMAO i would start a speed boat ride business
