Picking up from another thread. Out of curiosity how often do you use the greaser and how often do you put grease into the prop shaft connecting UJ's (I've got 4 nipples to grease on mine...ooh err missus).
I had it brainwashed into me from birth to do 1 or 2 turns on the greaser at the end of every cruise. I do the UJ's about twice a year.

I turn it once a day when cruising and about every three to four days when stationary - turn it until resistance is met not a specific amount of turns, could be two or three or could be just a half turn. Is that wrong?
Would like to know more about the need to grease UJs as I've never done so or been advised to (probably because I've never asked the question) - do all boats need this doing?

Not if they have a flexible coupling instead  |

Not if they have a flexible coupling instead Perhaps I could have phrased things better. Maybe do all boats need a separate greasing of the UJ's or do some set ups not need it. |

If there are grease nipples I would have thought they need doing. The question is how often? I have noticed more of a rumble from them when I have left it too long. |

If your boat has a UJ then I think the only negative aspect of being over-zealous in the greasing department is a very greasy UJ, which is better than a dry one. |

Isn't this a bit like asking "How long is your piece of string" as, in my experience, we each have to adjust to our individual boats ... there is no specific formulae.
After cruising with a mate one day I offered to drop into the engine 'ole and turn the greaser (he's quite portly, so the gymnastics involved would be easier for me).
"Oh don't bother with that, I never use it, it's almost impossible to turn".
I checked, and he was right ... never known a greaser so tight ... if it was mine I'd want to strip it down and see why.
Can you imagine the answer if you asked the question of him ... and it wouldn't help with your boat.

I would have said better to do it as your boat requires ... twist until resistance is felt ... one turn ... four turns ... whatever.
Doesn't take long to get a feel for it.

I try and remember to give mine a couple of turns every evening after a days running. (it stops any drips) If I can't put a couple of turns on, it's because the piston has reached the bottom of the pot and there is no grease left  |

UJs do need lubricating, years ago when I was "on the road as a service engineer" I picked up my freshly serviced Chevette from the garage.
I discovered a vibration coming from the gear stick. I rang the garage and booked it in for next day. Continued my day keeping the speed down and keeping an eye on it.
Almost got home needing to turn off at junction 3 and had just passed junction 4 when there was a horrendous bang, quickly I snatched the gear stick to find neutral and coast to the hard shoulder but...... it came off in my hand!!!! The car filled with smoke and with great difficulty made the hard shoulder.
Popped the bonnet to find the prop shaft had torn the gearbox off the car!!!
The cause was a seized up UJ
I was lucky the propshaft didn't drop and dig into the road or I would have been turning somersaults down the M4
Moral is.....use lube

GM junk. Almost as bad as the Viva HA that preceded it and that was truly awful. There are automatic self greasing cans that you could screw onto the stern gland and forget for a year but they would be a bit difficult spinning round on a prop shaft................ I never got to like the "sealed for life" UJs with no nipples, they had a very short life in my experience. |

Certainly and not just on nipples either. Did you know............. Baby oil is mineral oil based and extremely pure, thankfully. |
