- Twin Cummins 6.7 QSB
Just recently took delivery of a 2017 400 fly and looking for feedback on performance:
Twin Cummins 6.7 QSBs
@2700 RPM
80% load
38 GPH
Speed 18.2 knots
Props just refinished. Seems slow and fuel burn seems high.
Specs from boat test of same boat have her at least 23 knots and lower GPH.
Where do I start?
