I've been shoping around for a boat for years, sort of waiting for a great deal.... I stumbeled across a 26' Celebrity Andretti with twin 270 hp 350 mag's. Website says it'll do around 65 mph. My question is if I modify the engines to around 350 hp each or maybe 400 hp each (yes, i know i'll break my drives...) what sort of mph could I expect? I don't even own the boat, I'm just day dreaming. Can ya help me out! Thanks guys!
