4 strokes outboards IS THIS A MYTH?

The 200 V MAX is no fuel miser... so you are getting good fuel use there ..

Generally I dont think you can compare all these numbers as the conditions were different ..

It makes sense that the 150 uses more gas to go as fast or faster as the bigger motors ..

Yes Mat I agree with what you say.

I think the VMax is doing well as you say it drinks petrol like a bottomless well

However, the numbers showing the cnsumption of the 4-strokes are an indication that it may be a falacy that the 4-strokes have better consumption than the 2-strokes.

By the way the 150 Mariner is a 4-stroke

Here is a chart that I created a while ago ... all motors are Yamaha, 2 stroke, HPDI and 4 stroke compared to a optimax soprtjet ...

Your motor is the purple dotted line ...

You can see that the HPDI and 4 stroke are very simlar and differences probably come mostly from the boat rather the motor.

The 200 VMax is on a very light boat with high pitch prop thus very fast and very hungry (more as it would be otherweise)
