There were complaints of noise at idle with some of Hurth's V-drives when they were using ATF, so they recommended people switch to 15W40, same as the engine's oil. Either will work just fine. If you call Hurth today and ask them what you should use in your V-drive, they'll tell you 15W40 engine oil (at least that's what they told my dealer).

Water in ATF looks like a strawberry shake, water in engine oil looks like cafe-au-lait.

Ok so if I understand this correctly it is ok to run 15w40 in tranny also
ZF Hurth 63 IV-1.6
2002 Xstar
Haven't had any noise just would make it alot easier to only have to use one fluid

Thanks for any help

Greg

That's the same transmission I have and it came from Indmar with 15W40. To be on the safe side, I'd call Indmar before making that fluid switch.

i had this today as well. bought the boat this year. was checking the transmission fluid while looking at a few other things for winterizing it and noticed mine was bright yellow. it didnt look separated though it was a single consistency and the boat has sat for a litle over a month now.

If oil that was clear is now opaque and its color is similar to what it would be if the original color was mixed with white, water is in the oil and it was mixed while the engine/transmission was operating. The oil can't actually mix with water, but it can emulsify. This is the same reason mayonnaise is thick and white- it's materials that don't mix, but can become suspended after being agitated vigorously.

You'll need to find where the water got in and repair that before flushing the transmission. Replacing the oil without running it won't take care of the problem- it needs to be run with new oil and you need to make sure no water remains.

Collect some and look at it- if it looks like new oil, it's OK but if it's cloudy, it has water in it.
