Found an awesome deal on a 1996 tohatsu 50 hp would that be enough for a 1965 currituck that is being changed to a Montauk as we speak? Also what kind of performance can i expect.

Hi, Shane.
I calculate that you would have a potential WOT of about 32-33mph with the correct prop and rigging.
That assumes that your Currituck weighs around 1500lb ready to fish.
Red sky at night.. .

She is always ready for fish :).
I am replacing a 1984 Evinrude 65 commercial. I am assuming by your calculations performance should be relatively close.

I think JB is pretty close with his estimate.
My Montauk tops out at 33 mph with the Merc 50 4 stroke and a SS 4 blade Trophy Sport. I estimate my gross weight at about 1700 pounds. I am happy with the combination.

Shoctor, I had the 40 Tohatsu on my 17 for a summer. With the 13" prop, it cruised at 20 mph at 4000 rpm. With a tail wind I could hit 30 mph. If you can turn the 15" prop, you should be fine, but the 40 could not turn that big of a prop well. Great on gas though, 4.5 mpg. Good luck, those engines are bullet proof.
