Yamaha 150, 175, 200 carb differences

[madman2021]

What are the differences between the Yamaha 2 stroke 150, 175, 200 outboards? Is it just different carbs? Could I put 200 hp carbs on a 150 and make it a 200?

look up part #s to see what all you can find different between the motors

Or find an outboard racing forum to ask, they like to do the HP upgrade thing
