I saw this in the resotration shop at the Naval Aviation Museum in Pensacola back in '04. Does anyone know what progress has been made since then? Also why do the outboard engines have 3 blade props and the inboards have 4 bladers?

They told us on the tour what the reason was, I think it had something to do with water taxi but not 100%. There were a bunch of peole working on it, not sure how far along they are right now.

maybe the inboards are reversable props

That maybe. I do remember that they were not just doing a fresh coat of paint, but a whole restoration including the installation of alot of original equipment.

Took a walk through her about six months ago and the interior is coming a long but has a long way to go. As for the exterior the outer wing panels and horizontal were coming along nicley, the fuselage did not look that much different than your pictures. I was able to take a look at the float retraction assembly, pretty neat. The NMofNA is doing a first class job on the big bird.

I believe the odd prop arrangement has to do with water operation as stated in another posting.

According to Wikipedia,Matt is correct on the inboard props being reversible.Here's a link:

Sorry, that's all I have. I lost the majority of my pre 2006 digital pics in a computer accident :cry:

The wife was pissed because our honeymoon pics were gone too.

Sorry I was at the Museum on buisness and foolishly did not bring a camera, I will see what I can do in the next couple of weeks.

I once read that the four bladed props were added on the inboard engines to reduce cabin noise. Many of the Coronados' were converted to transports (e.g.PB2Y-5R) and the noise became too fatiguing for passengers ....including Adm Chester Nimitz!.

Howard hughes owned this aircraft for a while, and used it to train in for the Spruce Goose!

That is what I understand is the reason for the 4 bladed props.
