Simple questions on putting 110S saildrive together

[PembrokeshirePromise]

Hi,

I know the process of changing saildrive diaphragm has been covered many times on here - but they all seem to concentrate on taking it out - not putting it together !

I have the saildrive out of the boat and split - and took the chance to repaint it. About to reassemble.

The 110S has 6 stainless bolts clamping the diaphragm and no locking wire. It also uses an O ring seal to keep the oil in and then just metal to metal on the water jacket - aided by the clamped diaphragm I guess (guess if this leaks slightly its just water into water ...)
There is no gasket involved (at least until reassembling onto engine).

My questions are probably naive but:

1) Should I use any sealant (I have permatex) on the metal to metal seal of the water jacket.

2) Everything I have read says not to use any grease or anything on the seal - does this apply to the O ring as well (I have extensive experience of under water cameras and this is counter intuitive !)

3) As there is no locking wire on the bolts - do I grease the threads on these with marine grease, silicon grease or use the permatex - what about "locking" them as there is no locking wire. And does anyone know the torque for the bolts.

Sorry for all the question - but obviously its not something I want to get wrong !

Many Thanks
James

1) No,
2) I applied a spread of silicon to the new seal, as in dismounting the old one I found a generous spread of it put by the builder of the boat (15 years before, and the condition of the old seal was "as new"),
3) I'm not sure, but in an article on PBO (or, in fact, in the instruction annexed to the new seal) dating some 3 / 4 years, there was an indication of torque as well as order of closing the nuts on the engine-to-saildrive connection; for the bolts connecting saildrive and seal to the boat, there should be some hole in the bolts so You can pass some s/steel wire through, once You have secured the bolts.
Cheers,

(I did the job last year and the boat is still afloat......glu..glu...glu...)

I did this job a year or two ago: the only problem is that I can't now remember with certainty if my model is a 110 or a 120 (I think the latter), but from such memory as does survive...

There was a quite comprehensive sheet of instructions in the seal kit which covered most of this, including torque settings, where to put and where not to put sealant, etc. I'll have a look to see if I still have my copy.

Permatex was definitely required at one stage: I remember being annoyed that it wasn't in the kit and had to be bought separately.

Do your bolts have holes for locking wire? If so, I would definately use some (the kit includes stainless wire and a diagram of how best to arrange it). If not, some type of thread locking compound would certainly seem sensible, but others might be better able to suggest which type - there is quite a range.

Thanks Dave - I got the instructions for the 120 not the 110 hence some of my problems..

The bolts have no holes for locking wire - hence some of the questions - will permatex do this or do I need some other compound - to grease or not to grease -presumably locking compund will do both jobs ?
