We are doing so well on bilge oil and breathers, here's the next question:

I had the shafts and props replaced before buying the boat so half expected to have to adjust the stern gland up as they bed in. However, how often should I be adjusting them?

I have to do it after each run out in the Solent so far, that's why there is so much water in the bilge to mix with the unwelcome oil!

I am adjusting as advised to get a drip every 30 seconds (ish).

All advice gratefully received.

For some unexplainable reason our two boats show some very similar traits...

Brian,

Thanks for the info. Nick and I are both watching this thread with interest.

I was not aware that they should not drip at rest, I have been adjusting mine to drip every 30 seconds at rest. Of course when you turn the shaft it gets worse so this would be the answer to all that water in the bilge.

I was also not aware of any grease point, I will have a good look the next time I am onboard.

Unfortunately the new shafts and props were put on when I was not there so I have no idea what they packed the gland with. Perhaps an investigation job for the winter....

Look, they talk a load of crap. Who ever counted drips whilst going full bore. I just get mine to not drip whilst stopped. Well I try. But the bloody things always drip. Apart from the cleaver sods. Does anyone know different??

If you tighten the glands at rest such there is no dripping there is the chance that you over tighten them. The packing material needs a little lubrication otherwise it can overheat thats why its best to note the dripping at speed which, as has been pointed out, should be about 2 drips a minute

There's no grease point on moine either, think that's probably the case with most mobos. Replaced the shaft and stern gland 3 years ago, tightened it slightly just after launch and haven't touched it since, doesn't drip when stopped but plenty of lubrication when on the move, there's no way you can tell if it's 2 drips or 50 drips per minute when the shaft is revolving as it sprays everywhere, don't really care as long as there's water coming in.

If it does drip slightly when stopped why worry? Just make sure the packing isn't completely knackered. To replace it is easy if it is.

At last some sence. Though how it came from you god only knows. Mines got no grease nipple either. Just a water pipe to cool the gland. I also cant see how you would know how many drips whilst doing twenty knots. Think it's only the floor boards that hold everything down there anyway!!../forums/images/icons/laugh.gif

Aha Mr split personality bisexual is back, this time in his male form!

Mine's also got the water feed, forgot about that. Is MF back in the water yet? If she's still out she'll probably be blown back in today. Blowing an absolute hoolie today.
