2120 200 hp Yamaha Performance Chart

[beachbob531]

Could someone please advise where to find a Yamaha performance chart for a 2120 equipped with a Yamaha 200 hp 4-stroke? The dealer gave me a chart for a 2120 with a 150 hp Yamaha and it shows 3.4 mpg at its most efficient cruise speed. (The Yamaha website also has a chart for the 150 hp engine.) But I'm wondering what the milage is with the 200 hp engine. Thank you.

Those numbers must be with one person on board with no gear or additional weight on the boat. The best I can get is 3.2 with no extra weight on the boat going solo. I have alot of extra gear like 50 gallon bait tank rocket launcher etc and I get 3.0 at best.
