OK, so I don't do long trips, usually 2 hours give or take, and I don't always check oil, but I never tighten the nuts on the plate that press the stuffing box. So I got a boatyard (very experienced), to service the engine, and stated that far too much water was coming in to boat, at stern. He showed me how to tighten it up, unscrew outer nuts, quarter turn inner nuts 17 mm bronze. Stated this was part of daily checks, well I've never seen anyone doing this on YouTube, and not seen it on the forum either. I just can't believe it!
Obviously, it is barely accessible, and Ive done maybe 12 hours in gear, so really not a lot. Is this yet another thing they don't tell you, I assume the stuffing box is OK, I did ask..... I didn't sign up for all these problems, if its not the infrastructure collapsing around me, it's the bloody boat!

Are you referring to the stern gland?
If so, not a daily check, more an ongoing monitor, and if dripping becomes excessive, tighten the nuts as required, quarter turn at a time.
It's simple and quick.

Mr Boatyard removed the outer bronze locking nuts, the N did the quarter turn with 17mm open-ended spanner, I don't know if they were especially slack, but the point is that the problem remains, just as it was before adjustment. He may not have had the inclination to sort it, that's what a lot of people on the cut do when they have been paid, in my experience.

You'll see if you're getting more than normal water in, without getting into contortions I would expect.
Save the contortions for when you feel it's time to adjust the nuts.
I normally save any adjustment until I'm next doing a full service.

Cruiser stern wins every time for easy access. I as a matter of course check the stuffing gland when its out of water, I then carefully adjust the nuts, when the boat is in water I check to make sure that all is ok ie no massive leaks. The norm is a drip of water every 10 seconds or so, which should stop when you turn the greaser last thing at night. If you have no drip of water its possible the gland is to tight and it will be wearing a grove in your propshaft, its the water and grease that makes a bearing no water equals no cooling and something wearing out

It's the old style stern gland not the modern rubber gaiter type. There is lots of mucky water. I removed the oil absorbent mats, but the area is still filthy, and wet. I don't mean it has to be checked for water every day, that's no problem. Daily adjustment with spanners, to me that does not make sense, there can only be so much adjustment, the inner nuts hold the plate thingy, the outer nuts lock the inners. He is saying it needs adjusted every single day. THAT'S THE PROBLEM.

Yes it is certainly not a “daily check”, it is something to keep an eye on. How much bilge pumping is required gives a good clue to when it needs adjusting. I do ours about once a year max.

How much bilge pumping is required gives a good clue to when it needs adjusting. I do ours about once a year max. Before last week's adjustment I could hear it running on automatic once a day, 30 seconds, it was this that alerted me, I don't think it used to do that. My routine used to be to switch on the pump every time I started up the engine, just to clear any water. I feel that one should not rely on a bilge pump to stop the boat sinking! Mr Boatyard is adamant he is right and I am wrong, indeed he specifically suggested I look at boat maintenance forums. No point in ringing him again, he's not going to alter his position. I suggested that the stuffing box might need re stuffing, but, again he denied this, there is no more I can do, he's very experienced, I paid him a good day's wages, but I'm not sure what I can do, he adjusted the stern gland, and its still topping the engine gland compartment with water. If anything, I think its worse, also very greasy and dirty, I've run out of Gunk.

Are you sure that you are not just getting back some water which is already in the bilge but hidden? If you cannot see water dripping from the gland, then if it is not captive water, then you have a real problem, not necessarily with canal water. Where is your calorifier sited? could you have a leak there?

Nope, the engine hole is compartmented, so the only water that can get in to the gland compartment is from the prop area, I Don't know about dripping, I'd need to try to dry the area, then clean it, then turn engine on, see if there is a drip, put in to gear, and see this dripping, not convinced about this dripping, is it drip drip off the prop shaft, or what?

You could always put a tupperware box beneath. Put a bilge pump in it if you want to keep the bilge dry. Probably too early in the year for condensation, but that is often a problem in the colder months in an un-insulated engine room.

Not condensation, this is a very dry boat, plus its very very mild weather.

The daily check should be turning the greaser to your stern gland.
You have got a greaser?

Yep, I put my hand on the greaser at every opportunity, though probably not every time I turn off the engine, also I assume its only relevant when the engine is in gear, not when in idle eg charging batteries. Seems to me an awful lot of grease ends up in the engine hole. How much grease does one use in a year, I think I use less than a pot of Morris's. I don't do more than 300 engine hours, maybe 250 propulsion hours.
