OOO Sorry Nordy

I see what you mean.

The 4-stroke 225 Yamaha has lower consumption than the 150 Mariner. The Mariner however is a smaller engine (not in cc but out put).

From what i know (and please correct me if I'm wrong) the 225 produces actually less than 200bhp due to high gear reduction ratio. If you compare this motor with any 2-strokes 200 series you see that the consumption is higher (I think?)
