There is an interesting article re Titanic in the Saturday Mail of 31st showing the photo posted above,of the central prop being clearly 4 bladed. It also states that the sternmost funnel of the four, is a "false" one and not connected to the boilers in any way.It states that this fourth funnel was purely cosmetic,as she "looked better" with four rather than three.I hadn't heard of this before,but agree she wouldn't have looked right with three,but perhaps that is because I cant actually visualise it.I would have thought the funnels would have been bigger,and spaced differently if only three were used?

There is an interesting article re Titanic in the Saturday Mail of 31st showing the photo posted above,of the central prop being clearly 4 bladed.

There is no existing photo of Titanics screws known. However, it has always been assumed that this propeller had four blades as the one on her sister Olympic did, but nobody really know wether this was the case or not. There is an article about this qustion published by Mark Chirnside (for rivet counters only) 

A remark about the fourth funnel: although it carried no smoke it was not completely idle as it provided ventilation for the engine rooms. That "ventilation funnel" was one of the reason why the Olympic class ships had only very few conventional vents on her decks, which in turn is the reason for their very uncluttered appearance.

How's this, then?

This iconic picture is very often claimed to be Titanic. But it shows  Olympic... That's also true for many other pictures especially of the ships interior. As Titanic had a very short life and was not open for public prior her maiden voyage there were not many pictures of here interior taken.

That is the photo that was published in the Daily Mail article that I mentioned, and they were saying it was of the Titanic,and I agree with them that it is what they say. I cannot believe that the builders of the mighty ship would not have some kind of photographic record of her build,so I would disagree that there are no known photos of her props.

I quote Mark Chirnside, who has published some highly regarded books about the "Olympic Class" ships:

When Olympic entered service in 1911, her propellers were photographed and these well-known photos show her turbine-driven central propeller as a four-bladed casting. In Britannic’s case, not only is a four-bladed propeller visible in period photos, but this propeller is also visible today on the wreck. However, at present, no known photos appear to exist showing Titanic’s propellers in place and, given that the central propeller is not visible on the wreck, this raises an intriguing question.

As Titanic was the second ship of her class she got much less attention prior her maiden voyage than Olympic which was the first of the trio. That's why it is very realistic that no photo of here props has been taken. It was pre-digicam-era...

again, the picture in the dry dock  shows Olympic. That's also a well known photo published in many books as being Olympic (Titanic never had a white painted CWL...)

If thats the case then the starboard prop is a two blade?  I think the centre prop is a 4-blade.

I,ve yet to meet a Tadpole or a Stickleback,that can tell the difference,between a 2,3, or 4 bladed prop, wether it be plastic or brass,
