Weeping Shaft Plates.

[steverow]

Hi all,

Just gone back in the water on Sunday after being out since November with various jobs being done...hull epoxied...bowthruster.. etc..etc.
Late on Sunday afternoon doing our pre-leaving the boat type checks I noticed that there was water weeping slightly from around the rectangular plate surrounding where the shaft goes through the hull (I think theyre called shaft plates..rectangular things with bolts through 'em) in the engine room.
I reckon it's weeping maybe half a pint an hour from near one of the nuts.
Nuts cant be tightened as it looks as if some previous owner has epoxied them in.
Now as the rear sling was just forward of this my guess is that probably the lift in may have caused some movement.
What is the consencus of denizens of the forum, is it likely to settle down as she settles in the water over the next week or so, has it happened to anyone else? is it likely to get worse..or should I have her lifted out again and looked at... at vast expense..well a few hundred quid anyway...
Great to be back in the water by the way...and thanks to Gludy and me other mates for helping out.

Cheers

Steve.

You must have a stern gland, that's where the nuts are. Should be some studs sticking out to which the nuts are screwed onto, usually 2 nuts per stud.

I expect the packing has dried out a bit, maybe the hull has flexed on lift out/in and compacted the packing. Don't expect you need to get lifted out again, some grease may do the trick or a few new pieces of packing should also stop the leak. The nuts must come off, can't imagine that anyone would epoxy them on.

Get someone proficient to look at them, should be an easy job.

Hi Steve
Sorry to have missed you at the weekend.
I was at the Marina today and Pegassus was still afloat!
I couldn't rest if I knew that the boat was leaking no matter how slight, Sods law says when you need to get to the boat to do something, everything else gets in the way!! and that could be to late!!

Yep thats the thingies...stern glands.
It's not weeping from the gland nuts themselves...ie the Big inch and a half things
on the shaft, I'm used to dealing with that..but from a small area around the nuts holding the whole assembly to the hull bottom. The mounting is a rectangular plate with maybe half a dozen nuts each side, which the stern tube assy is moulded into..is the only way I can describe it.

Just typed in Stern glands into a search engine, and one site that came up was this.

Bit canal based but very informative all the same.

Cheers

Re: Weeping Shaft logs

you will have to check shaft alinement

If the bolts are thu hull and you think that the hull may have been warped then any thing that is loose will only get worse with running
