I have the standard fuel setup 33/10 gallon tanks. I have a 225 proxs with a fury4 24″. Holeshot is awesome and will run 70 loaded heavy. I have seen 75 but it was cold and the boat was light. The boat sits a lot flatter in the water than my buddies rear tank caracal. I came from a p2 to my caracal and I like the extra room.
