Curtiss SC-1 Seahawk question.

[Jerry O'Neill]

I have a question I need a quick answer, What is the diameter of a Curtiss SC-1 Seahawk Propeller and what engine does it have?
Any photos of the front end would help.
Thanks.
Jerry

The question arose from a friend of mine who is doing some research on odd uses of airframes. He was wondering if the whole powerplant assembly from an SC-1 would've been simply attached to one of the ex. MGM wind machine Dauntless' or was the prop just attached to the Dauntless' original engine. Also, is it really an SC-1 prop. Since NEAM doesn't have there Dauntless any more and it's now at Weeks I couldn't go an get any measurements. I was pretty sure it was an SC-1 prop due to the short diameter of the prop assembly.

Thanks Paul, for going out and measuring the Dauntless for me with out any calls!
Thanks for the help guys, isn't WIX great!
Blue skies,

Nice work, Jerry...my brain had never made the connection as to the Weeks prop being off an SC-1.

Here are a few close-up looks for the motor experts.

First, US Navy pic of SC-1 installation:

Here's another with prop & cowling installed (don't forget to zoom in):

And here's a couple of the Weeks SBD:

Off to work. Perhaps another WIXer could pull up a decent SBD motor pic to solve this.

Thanks for the posting Dave.
I was on the Curatorial Committee at NEAM back in the 1980's when we all decided to sell the A-24(SBD) to Kermit along with our PBY, Someday, I hope to see both in the skies over Florida!

Here is an original wartime Curtiss Seahawk 3-view, fom the Curtiss Company files. While looking through the files, I noticed some surprising prop sizes. The SO3C-2 & 2C used a small two-blade prop that was Only 8" 10"...

[Jerry O'Neill]

Does anybody know if they used steel hollow blades, solid blades or both? I know Curtss Electric made both type.
Any prop experts out there?

Did any survive post war?

[Jerry O'Neill]

None that I know of.

Did any survive post war?

They served aboard some ships into the late 40's. As for civlian SC-1's there was purported
to be a surplus one spirited away to some guys place in Canada...dunno if it's true.

the seahawk while physically beautiful......... & technology wise forward as to performance did get a toe in the action toward the end of the war. it was not a lumbering ass dragger as most flying boats & seaplanes are portrayed. i'm biased for aquatic aircraft, i love their lines in the water & on pontoons. sad to say, but i doubt none survive of this type.
