This older thread has a 33 tested with 400's. You can probably use Bam's Speed Tester to figure out the rest.

radar test showed 69mph.

yes I can see you can read from the boat test I scanned..
I am gving the BRAND the benefit of doubt because I like Sutphen's...next...
P.S. this is the "old guy".....

Test boat was an 85. A late 80's 33' might be a little faster.

i can read,image that and i can drive my boat w/o flipping it too.

key word is "drive"....running Sat with us??, time to get the cob webs off the Whipples??

Hey Billy , behave! And Ken, Billy and Paul will be slowing me down, so it looks like you will still be just slightly faster than me , if I could lighten the load you would not stand a chance!

Good deal, just took delivery of a 33', needs a pair of engines and didnt know how crazy i would have to get to make it move. Twin 500 horsepower engines should push it high 70s then?
Finishing my Apache, then starting on this one. Cant beat classic boats, great lines, built tough, pound though anything.
