[QUOTE="turne032, post: 225430, member: 1355"] inboard vs outboard "my theory" the point at which the pump loads has to make a huge difference. As a inboard pump loads about 2 feet in front of the transom and the outboard is 4-6 inches behind the transom. If an inboard is bouncing (porposing) it cant load the pump. No water in pump means no speads out of the pump. I think power to weight ratio has a big part to play in performance as well. I would really like to measure the speed at which water exits the pump on a 40 hp vs 200 hp vs inboard. (my opionion is that the water speeds are closer than what we think. The difference being the volume. But then again i have no proof for my theory) there is a point in which the motor is too much for the boat. The result would be the boat taking off like a kite. its similar to car drag racers trying to put the horsepower from the motor to the tires on the track. [/QUOTE]
