shaft seal (Volvo?)

View attachment 10572

This is a newish boat to me and I have only recently got as far as considering the shaft seal. It hangs off the back of a 40HP Volvo. Is it Volvo seal?

Is it the sort that needs 'burping' and if so how do you do it?

If any of the rubber bits fail are you suddenly on a downward track to the seabed or is it less dramatic than that?

What oil do you use?

(I do have a manual but it's a long way away)

It's not a Volvo seal.Don't know what that is,maybe someone here will.

Its a Halyard HMI shaft seal , no need to burp it just change the oil in it once a year if poss , when ashore . Check for oil leakage and the condition of rubber bellows , had one fitted to my yacht for 14 years good bit of kit , they are no longer made and these seals are getting old now for that reason alone replaced mine with a PSS seal which also seems to work well.

That's the sort of thing I wanted to hear.

Does anyone know what happens if one of the rubber bits split? Is it a deluge or a trickle?


thanks

Is that an optical illusion, or is there a massive misalingment?

You're just trying to ruin my night's sleep,aren't you?

Optical illusion, I think. Runs very sweetly and recently checked by an engineer.

I am very pleased for you and hope that you sleep soundly, do you agree that the pic makes it seem out of alignment, or do I need to go back to sleep?

Having looked again, you're quite right. It looks like a photo from a 'how not to do it' lecture.
