4 strokes outboards IS THIS A MYTH?

Zitat von Manos

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?)

Not to worry here. The 225 produces 225 HP at the shaft ... the different gear ratio will mean different torque thus larger prop .. in the end there shouldnt be a fuel use difference based on that ...

The US are adopting a law that motors can not be underrrated as much anymore. This was done to look good in tests .. so pretty soon motors sold in the US will actually have the HP they are rated for .. IMO 2006 or 2007...

P.S. They make a 300 HDPI now .. maybe thats the motor to get :)
