I just changed the gear oil and went for a ride. Went through some pretty deep water a few times.

You can see the oil is a creamy color in the sight glass - like water got into the casing somehow - or antifreeze, that would not be good.

Any ideas on what happened.

Did you happen to see what the oil looked like after it sat overnight?

That could well be aeration, tiny bubbles making it look cloudy.

Thanks for the responses - my gearbox noise also went up when I noticed the issue - flushed the gear oil - since changing the gear oil no more problems, gear noise back to normal - still frothy which is apparently aeration

Gear oil turns this color when condensation/water get into it. Did you recently have some extreme weather temp variations or change in Humidity while in operation? Also, make sure the fill plug is snug.

Because of this discussion, I replaced the gear oil today (it was after I accidently submerged the bike, don't ask..).
The used oil was grey and creamy. Replaced it with a Liqui-moli 75w.
Look at the photo, the difference between the old and new oil is quite striking.

I think the creamy color was before the bike was submerged, but I am not 100% sure.
