Wow!  :o You're an information junkie! Much like myself! ;D ;D

tjc360:
Any have any #'s on a 233 w/ twin Merc 188's(302's).   Just commited to purchase but not exactly sure what I'm going to do with it.

These damn classic hulls get me to do things like that.   Mako, Formula and even an old Checkmate......hell, my boats are the "70's Show"  Thankfully , I don't know anyone w/ a Bert for sale "cheap".

sanddragon2004:
so is it safe to say if you built a 330+hp small block you could potentially see those same 60mph speeds in an f 233? i was thinking a 355ci 370 hp small block in mine.

Klas233:
Don't know if it is "safe" to say, but I guess it's possible.

Klas233:
The very first standard Formula built, #16 "The Cigarette" raced by Don Aronow's should be added to this list:
55,6 knots, 64.7mph (GPS) 1962 Formula 233, with a 409 block Mercruiser
If you haven't read it already you should all read this great article about the restoration of the first Formula ever at historicraceboats.com/membersboats (HORBA)! http://historicraceboats.com/pdf-mo-pokerruns-v9n5.pdf It has some beautiful pictures of the boat!
