When F1 reduced their engine size from V8 to V6 this year to reduce fuel consumption of the cars I was thinking why the boat companies don't do the same to our boats? I think i speak for most of us here when I say we want those 409 (450 sometimes) horses for both slalom and jump but isn't there a better way to get the same amount of power from a smaller engine, like a turbocharged V6 or likewise. Are they doing any testing with this? anyone know why it would work or why it wouldn't?
