Stern gland questions.

[ExUserGone]

Being used to outdrives I need to ask some stupid questions....
Does anyone recognize this type of stern gland?
It's water injected and has no greaser, what will the other pipe be for? (the one that goes straight up)
Do I need good insurance and diving gear to repack in the water?
Graphite cotton or ptfe flax type packing?

Being on a boat I would of thought you need tto pack it £20 notes.

 

Is it water fed from the engine, if so the other pipe might be an overflow /vent pipe ??

Yes it is water fed from the raw water circuit.

I'm no engineer but am I right in thinking its a purge pipe that allows air to escape? Where does this pipe go? does it extend above the waterline?

hi,

if you try to repack it in the water ,the water will tend to push the packing out!! and if your unlucky you won,t be able to get the new in.....as you don,t know what,s in there now ,you need to to find this out first ,out of the water would be better then remove a turn of old packing and meassure it, the packing gland looks very near it,s limit thou,need name of gland? and size to make a call on it.

It looks like a stuffing box on the forward end of the stern tube. If its fed by water from the engine then its likely that the bearings inside the tube are cutlass bearings that need water lubrication. I have not seen a stern gland of this type with the two pipes going to it. Most glands have just the one pipe or tube going to it and will have water going through the pipe if its a cutlass bearing type or grease if its a bronze bearing type which is quite rare now. As has been said it would be good to know where the pipe on the right goes to. To repack the stuffing box the boat would need to be lifted out of the water. The box would take about 3 strips of packing and needs to be adjusted so that the gland drips once every minute or so to prevent the packing from heating up.
