There seems to be confusion on which oil to refil on a MS25S saildrive. Manual says same as engine oil, other sources say Synthetic oil. Anyone know the correct oil?

I confirm that the manual specifies CE 15W40 which is the same as engine oil.
I have the same saildrive, which was professionally serviced and the engine oil was used.
Given the light use of a saildrive the engine oil is perfectly suitable. Careful because different saildrive models require oils with lower viscosity or Synthetic oils. This is NOT the case for the MS25S.
despite the fact that it would be more sensible to put in the oil that VP recommend?I'd keep using whatever is in there now.
perhaps that is the correct oil for yours ... you don't tell us what type it is !My box has the red synthetic oil in it.
ATF is RED? Synthetic Gear oIL IS NOT SPECIFIED for MS25s gearbox, either same as engine or ATFSorry Vic, on the basis that I was replying to a thread regarding a Volvo 2020 with a MS25S gearbox fitted I thought it was obvious what gearbox I was talking about.
Also, on the basis that the two oils look so different i.e engine oil is golden, synthetic oil is red, and that there do seem to be two choices, I thought it sensible to keep using whatever was already in the box.
When I last changed my oil I was specifically asked by the Volvo dealer what oil I already had.
ATF is RED?
You misunderstand my post, perhaps my ? should have been ! Volvo Synthetic gear oil is not red, but Volvo ATF is red. 120SD should have Engine oil. 120SE is synthetic.I never said that ATF is red.
What I know is that this is my engine/gearbox/saildrive info:
engine MD 2020 5102329755
saildrive 120 S-D 2.48:1 3582395 MS25S 2:47 5025-01-30018
and that two Volvo dealers have supplied red synthetic oil which replaced red synthetic oil.

Probably doesn't matter what goes in as long as its not water? My last boat had 120SD in which I always used engine oil, VP dealer did supply Synthetic for a spares kit, new boat (7 years old) has MS25 and uses ATF.Well that's me screwed then.
I appear to have a 10 year old 120SD in perfect working order that has always had red oil in it which both Volvo dealers called synthetic.

That's interesting. All the literature and owners manuals shows them as complete units either a 120S or a MS25S. The earlier engines being fitted with 120S units and the later ones with MS25SI have a Volvo MD2020 which according to the rating plate on top of the gearbox has an MS25-S GEARBOX WHICH IS ATTACHED TO A 120S-D SAILDRIVE
