150Hp Yamaha 2 Stroke EFI, how bad is it on fuel?

[C-NUMB]

Have heard the carbed version is very thirsty, 60 + liters at wot...How bad is the EFI version
(not the hpdi) is it all the same? Anything particular with the EFI model, worth knowing, good or bad?

i would imagine wot on a 6.5 mtr more like 100 litres p/h

..more like 100 litres p/h,,that sounds really scary. As the 2 stroke 90 would max at approx 35 l/h seams strange that one 150 would use almost as as much as 3 x 90 hp.

But the 90 hp is as economical as a carbed 2 stroke can ever be , maybe the V6 is just not that good design, at least not from the consumption point of view.

the carbed 90 was pretty reasonable

The V6 Yam is 2.2 litre or something like that which is a completely different beast, i have never owned one so i may be wrong but interested to hear from someone who has nailed one for a hour to put us right!
