Why is it necessary to change the oil annually if it is not contaminated by water ingress? I do not need to change the oil in the gearbox or back axle of my car and cannot really see the difference.

Due to the (equivalent of) "crash" nature of the gearchanging in your saildrive gearbox, there is a much higher probability of metal particles being chipped off and therefore creating accelerated wear. So the oil needs changing at regular intervals to remove this. Also, quite a high degree of water contamination can occur before the tell-tale milkiness of the formation of an emulsion becomes evident.

Sorry to disagree, but a Volvo saildrive doesn't have 'crash' gear changing as it uses clutches which synchronise the speeds of the moving parts before fully engaging gear.
A lot of our sail boat folk only lift their boat every second year and so change the oil bi-annually.
A sail boat drive lives a very stress free life in comparison to a motor boat so there isn't much wear taking place, there are dozens of saildrives 15 years old or more still going strong.

Both my 120 saildrives have had only 3 oil changes in 12 years, if it looks and smells good when dipped, why bother?

I would agree with others: unless a seal's gone letting water in, the leg oil always look the same at the end of the season as the start. Given, however, that you empty it out annually to check, I have been wondering if there is any merit in replacing it with fresh, and use the old leg oil (if apparently water free) as "new" engine oil. (The type is the same and the quantities - VP2002 - almost equal.) Any thoughts?

I don't empty it out to check, if I did I'd put in new, as it's such a pain to fill anyway it would be pointless putting back the old oil. I just check it from the dip stick.

Well,
MY gearbox takes synthetic and my engine takes 20w50 mineral, so where do we go from there?
Not good to comment here unless you get your facts straight.

DO remember that...
the "leg" oil is the same as the gearbox oil. IT ain't just the bottom of an outboard, you know.

Steve,
The preaching bit on population, CO2 etc is heavy going just once in a thread but several times is over cooking it. Can you remove or change the preacher line...if you want folks to read your entries, that is!

I was describing my engine, and to make that absolutely clear I said"(The type is the same and the quantities - VP2002 - almost equal.)". Now just what facts do you assert I haven't got straight?

Re: Your comments
Steve,
Last night you posted two aggressive / supercilious comments about one of my posts. I asked you to explain what prompted these. Your reply to Peter Gibbs confirms that you have viewed the thread since then, but you have chosen not to reply to me.
I would ask again that you justify your comments. Alternatively, if on reflection you consider that they would have been better not made, then a brief withdrawal and/or apology would be readily accepted.
If no response is received in a reasonable time I will regretfully mark you as "Ignore this poster" - something I have never previously done.

Because,
you kept referring to "the leg" when a lot of people think that they have just the bottom part of an outboard stuck onto their engine when they have a saildrive. Seems you don't think that. However to call the high viscosity synthetic gearbox oil "The same" as the multigrade mineral engine oil is totally inaccurate.

Re: Because,
The Volvo manual for my engine clearly states that the same oil is specified for the VP2002 and the saildrive. You say that is not the case for your engine / saildrive.
If I was to follow your line of reasoning I would deduce that you must be mistaken and clearly don't know what you're talking about.
More rationally, I would suggest that we simply have different engine / saildrives with different oil specifications. Indeed, another poster has helpfully pointed out that from a given date Volvo changed their specification, which would seem to explain the apparent anomaly.
Apology, perhaps?
