305 vs 350

[Chris]

I have a 2007 Sea Ray Sport 205. I have to replace the motor because failed to winterize boat. The one knock I have on the boat was the hole shot. Need more power to get bigger skiers up and going quicker. Considering upgrading from 5.0 to 5.7 carbureted engine but wanted to make sure that I wouldn't be causing another problem with drive etc. Looking for recommendation on what to do.
