Dp-G Ring Anode and Prop nut help

[jon and michie]

Hi - Has anyone noticed or come across different size anode rings for Dp-G drive as in the thickness from the propeller to its base on the drive?
I am asking this as I have a nagging doubt that the gap between the propeller and the ring seems a tad excessive (I did follow the volvo manual for correct install)
my next part what I noticed was the Nyloc Nut - Now Volvo serviced my drive last March and I took the props off late Early February this year what I noticed was it seemed that the nut had been well tightened - when I came to put the props back on I got a new Nyloc nut from keyparts and so I came to tighten it up I set my Torque wrench to 70nm as per Instruction but I then noticed that the shaft was level with the nylon end and no threads showing.
As I dont want a repeat of the other year I am thinking I will strip back down and rebuild the props back up just to stop any nagging doubts.
So does anyone have a DP-G manual or know if there is a specific dimension/size from the edge of the forward prop to the anode base as this may give me an indication if all is well.
I do apologise for babbling on - its that I am away with work and wont get to the boat for another 2 1/2 weeks and its is driving me mad
p/s The anode ring that I just put on was a MG Duff - obviously the previous one was a Volvo anode could there be differences in sizes and the same for the nylock nut could the one from keyparts be different in height size over volvo ?
(please note the photograph was taken last year showing the volvo anode)

I thought you rear prop was on the wrong way round but now I don’t think it is ??

The important thing is that the first thrust washer is properly located in the prop, and that the rear face of the nyloc nut is making firm contact with the prop hub.
For a new nut, I would set the torque wrench to 80Nm and apply some arm power.
The actual gap between the anode and prop will depend on the anode dimensions plus where the prop sits on the hub - it’s not a precise thing.

Hope not - that was Volvo's work last year!

Thanks for your replies - what is annoying me more is that it is one of the easiest jobs to do - arrrggh.
Another question is the first thrust washer to go on over the splines has a small indented profile on the outside edge - does anyone know why as I can't see where it lines up in the prop hub.

Right as an update - removed the first prop (the rear one held on by the cone) Then I noticed that on the 2nd prop the nyloc nut only had 1mm of shaft thread past it -here I was thinking had the thrust washer not seated properly in the prop hub and compared it to my old outdrive and prop photographs which showed between 3 and 4mm of thread past the nyloc.
Fortunately the thrust washer was correctly seated so began to take measurements the first was the shaft length from the collar where the thrust washer sits up to and then the internal hub including the thrust washer and the height of the nyloc nut.
which gave me 1mm spare - so after all that nagging doubt I was correct in the first place - However volvo have either changed the drive shaft length or the hub size on the propeller (I'm thinking the latter) .
I will update with photographs later.

Here is the Nut showing not much thread - This was what gave me the doubt.
