I have a Perkins
M90 attached to a gearbox
of unknown brand. The yacht is an ex Moorings 505. (Beneteau 50)
is likely a
Newage PRM 500D or
ZF-Hurth HBW 450A
but not sure as I cant see a model
On the oil
filler the gearbox has a sticker "ATF".
When I bought the yacht the advice was to put a light engine oil
in the gear
box which was done.
It looked like engine
oil in the gearbox when I first drained it after buying
I change the oil in the gearbox regularly at about 400 hours.
It works fine and I have done a bit over 2,000 hours in the last 18 months.
There is lots of stuff on the net about Engine oil Vs ATF.
What is the definitive advice?
THERE IS NO NEED TO BARK IF YOU HAVE A DOG
