Fuel burn was definitely one of my main goals.

Is this accurate? The only difference b/w the 350 and 400 is peak RPM? Does this mean that at cruise speeds (less than 6k RPM) they would get identical fuel mileage?

Overpower as much as possible. If your not getting trips then get the twin 400's.

I have quad 400r's on a yf42 and love em over the trip 350 yammies I had on the last one.
More power= better hole shots, no prob getitng on plane when loaded up, less strain on engines, can run at lower rpm's, generally better fuel burn at cruise, higher top end-- everything better imo.
