Quick answer
SkipperCalc has 7 sourced Sea Ray configurations in the picker. Use them as a starting point when you do not know your exact fuel burn, and replace the figure with your measured burn when you can.
- Sea Ray 260 Surf · 1 × Mercury 8.2L MerCruiser
- Sea Ray SPX 190 OB · 1 × Mercury FourStroke
- Sea Ray SDX 290 OB Sea Star JPO · 2 × Mercury FourStroke
- Sea Ray DAC 320 · 2 × Mercury 6.2L MerCruiser
- Sea Ray SPX 230 OB · 1 × Mercury FourStroke
- Sea Ray SLX-R 310 · 2 × Mercury 400R
- Sea Ray SLX-R 350 · 2 × Mercury 450R
Practical rule: compare L/nm or €/nm, not only L/h, because speed changes cost per mile.
