Over the same distance my 200 opti used 51 Li and a 250 etec used 90 ish or so we think

No chance, coz I'd not have made it back to Fal at that rate. I was robbed by that pump attendent at Mylor.

Yeah, I've heard that the 150 is particularly thirsty and that a 200 HowlinMax enjoys the odd starter motor.

For those that don't know I went for the Suzuki 200. On a good run I can just touch 47 knots and am using an average of 1.1 liter per mile. There's about 500rpm spare so I might try a smaller prop or raise the engine a tad.

Petrov should know, but the 6.5 Vipermax is rated to only 200hp. Most hit around 50kt with a 200, set-up for leisure use, so I reckon a 250 set-up similarly should get around 55kt. Would depend on set-up, loading, etc and whether you wanted all round ability or out and out speed.
Some info here:
