You can never have too much power, but I am sure GW isn't going to dictate that. As the future owner, I am sure you get to choose whatever you would like. BTW my 33 w/ 250's isn't under powered ( and I've heard they aren't even w/225's). I cruise at 30 top out just under 40 and get 1.1 to 1.2 mpg. I am rarely, if ever, passed by a similar class boat. The center consoles w/trips do go flying by me. That's not to say I would mind the new generation 300's.
