Matt this is
E X C E L L E N T!!

Thanks for that!
I wonder what would it show if we had a chart for a boayt weight 1800kgs and different motors such as:
Yamaha 250 HPDI
Yamaha 225 HPDI
Yamaha 200 VMax
It will be interesting to see as we all now think that although the 200VMax is thursty on my MAR.CO is not more thursty than the 225 HPDI or even the 250 HPDI that they had on it before.
In any case is a very good dat. Many Thanks
