JP, We also have the 97 330 with twin 7.4L MPI engines. We also like to cruise between 2800 and 3000 RPM which decreases our burn rate to about 25-27 GPH and it is a comfortable ride and still gives us good maneuverability on the water. I just cannot imagine what life on the water would be with a boat this heavy and smaller engines! Again, for us (me and The Better 9/10ths), it is all about the journey and not how fast you get there! Good luck in your search and let us know where you land with your decision!
