most similar size engines are quite similar on consumption at wot, its the cruising range that makes the difference for dfi and fourstroke engines.
i should imagine your 225 is having to work quite hard to push that boat along so a bigger engine will probably prove more efficient for fuel .....depending on which one you go for!
on yes and on the survey it averages around 1l per mile on a 6.5 vipermax with 200 opti with typically two adults and two children and typically full of fuel and more pies than you can shake a stick at!
