I know most of the P-47s had Curtiss electric props,(some had hydo props). Can anyone tell me which variants or block numbers had the Curtiss and which the Hams? Or tell me where to find the info?
Thanks,
Hugh

I can't break it down to block no.'s, but the late model P-47D is when either prop became an option.

Curtiss - C642S Hollow blade 13' dia.
Ham. Stand. - 24E60 13' dia.

Regards,
Mike

While it may have been done by block at the factory, I recall hearing that switching these in the field was somewhat common, so it's fairly difficult to pin these things down barring access to RAC records on the matter (do records like that still exist?)

I figured it would be hard to nail down, but didn't realize switching was that common. Anyway, thanks guys.

When in need of an epiphany, search the Baugher Bible:

Beginning with production blocks D-22-RE and D-23-RA, a larger (13- foot diameter) paddle-bladed propeller (either a Hamilton Standard Hydromatic 24E50-65 or a Curtiss Electric C542S) was fitted to make full use of the additional power provided by water injection. It added 400 feet per minute to the climb rate, but during landings and takeoffs there was only a scant six inches of clearance between blade tips and the ground. Takeoffs and landings must have both been hair-raising.
