Default engine question 2bbl or 4bbl carb

Ok,my family and friends think i've gone nuts,as i just bought another boat,which now makes four.

Actually i bought it for the engine and drive,for use in my 23 Tsunami.it's an 18-1/2' Chris Craft scorpion with a 350 cubic inch Mercruiser engine with an Alpha 1 outdrive.

The engine was put in about five years ago,along with the drive and have only 200 hours on them.
We took it out for a test drive,and everything runs and works perfectly.

I paid 1,500 bucks for it,so i figure that's a lot better than spending 11-13 grand for a new package.

"Anyway now my question; the engine only has a 2bbl carb on it which makes it approx 230hp.
It pushes this boat at a top of 50mph,but of course it's a smaller lighter boat than the Tsunami.
I'm wondering if will it be enought to push my 23 Tsunami at a reasonable speed with the 2bbl carb.
I have a nice Edelbrock 4bbl marine carb at home,and was wondering if i should put it and a new intake on it now, which would give me around 260hp,or try it with the 2bbl first,and see how it go's,and then go the 4bbl route if necessary.
Any thoughts would be welcomed.Thanks all.
