Can anyone tell me how often they are changing their gearbox oil?
 
I had it changed 18 months ago for the first time ( as recommended by Hanse ). This is apparently because a new saildrive will have all sort of bits floating around in the gearbox after a little use.
 
I was going to change it again this season ( about 100 hrs use since the last change). However my friend who has been sailing for years and years says that there is no real point and that you would be better off just topping it up.
 
Over to you.
 
Many thanks.

Hi Nick,
 
I just called the Yanmar agent and they say it should be annually or every 150 hours depending in what comes first.
 
Cheers

Interesting Phil. Is Nick's model different to mine or perhaps Yanmar have changed their requirements?

My handbook for the SD20 requires oil change after first 50 hours and then every 100 hours of operation.

As I understand this "policy" from Yanmar, the first oil shift is due to wear-in of the gears, and possible metal containment in the oil. After this, a yearly/100hr replacement is just to verify that there is no water ingress in the oil. The oil itself is not subject to "being worn out" - as the case would be for the engine oil.

However, I personally replace this oil on a yearly basis - as it may contain some humidity or water. (This year the oil actually contained water, whereas I replaced the shaft sealant/bearing (?) to rectify the leakage.)

How do you manager to exchange the oil after 50h if it is in the middle of the season?
As far as I have understood, you have to take the boat out of the water for that purpose - a quite costly change of oil.

This is why i posed the question. The first time i changed the gearbox oil, I had to get the boat hauled and the "Yanmar" engineer spent an hour trying to find the oil drain.
I am hoping that a sump drain pump will be able to do the job through the oil filler hole.
Anyone had any joy with this? As with most jobs on my boat, I imagine that I will end up covered in muck, looking like an extra from the cast of Oliver and phoning my chiropracter from A&E.

It is posible to change the oil wenn the boat is in the water , there are two points on the drive in the boat one on top and one just above the manchet . On top you press air throug and the one below there will come out the gearoil. See for it in the manual wich came withe the boat/ engine or saildrive.
I just did it a month ago and it works perfect

I have recently noticed some air bubbles in the oil of the s-drive and thought that some water penetrated through the prop-shaft seal, besides the oil level slowly went down so I thought that the seal cannot withstand the pressure from the heat expansion of the oil...therefore i created the open system with the expansion tank to make sure there's no pressure inside the drive (there's another thread on the matter)....

But I have also decided to change the oil in the drive to check for water ingress (the boat was on the water)...this is a pretty tough work to do...you need a vacuum pump and you need a super-tiny hose to be able to slide it between the gears...as it is tiny - the oil flows very slowly and you need to preheat the oil to make it less viscous...finally i managed to suck off 2,2 litters which is almost everything that was inside...so  if the boat is on the water, I can definitely say that it is possible to change the oil - yes it is much harder and time consuming but much cheaper if you compare with crane fees...

 
Addition...Marcel, I belive you have an SD50 on your 370 which has a system to blow the oil off...on the SD20 there's nothing but the oil cap, so see above...
