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)
