I have a 33ft V bottom thats looks like a Concept and runs 72mph @ 6,200rpm with twin 300x's and 4 blade Bravo 1's with 1.75 gears on it. My friend has the same boat but when he built it he set the gas tanks further back and the Centet Console 6 inches back as well. Now his setup is 3 300x's with 28 Choppers 1.62 gears and his boat weighs about 500pds less than mine and the boat runs 93 on GPS why is there such a mph difference I know he has triples but if I put tripples i will only gain 8 to 10 mph at the most. Is it the gears or the props?
