I would go bigger. Our first Ski Centurion Warrior Barefoot (which has a very quick-plane hull) had a carb Yamaha 225. That was really nice, until my Dad sold this to my brother, and had another carb 225 on the Centurion Falcon Barefoot.
Jim put a Yamaha 3.1L EFI on the Barefoot Warrior and holy smokes. Great motor. Starts great, idles great, runs great, tons of torque. So much so that my Dad put one on the Falcon and it was a game-changer.
You can get by 175, but ideally I'd go bigger. Prop choice will be important(pitch) on a 175. It will be a fun boat tho.
