Is this water in my gear oil? Volvo DuoProp outdrive. I replaced the oil with Volvo Penta OEM gear oil at the end of last season. The oil came out looking like this after being wet slipped this season.
Doesn't water settle to the bottom? Does Volvo gear oil change from honey yellow to dark black as it is used? Is the green coloring water intrusion? This oil has been sitting for about a week so I was expecting to see water at the bottom, but I've read that the gear oils are formulated to keep up to 10% of water suspended. Is this so?
Volvo gear oil is honey colored and very light. Mercruiser oil has a green color to it when new that darkens as it gets used. I was thinking maybe the previous owner was using Mercruiser oil so this is some of the mixed residual oils as the drive was used and the gears spun, but I recall last year the oil came out rather dark.
The drain plug o-ring is extremely small on this drive and it typically gets pretty beat up after it is installed, so could it have come in from there? Last season the o-ring came out looking the same though. It was the proper volvo penta o-ring as well. All 3 o-rings get changed each season with Volvo Penta OEM proper o-rings.
What am I dealing with here? Is this definitely water intrusion? Should the water be settling to the bottom after being in a container like this for a week or two? The container I poured the oil into had a little residual antifreeze in it so that may be floating up top as well, but it minimal.
Debating if I should pull the drive and pressure test it.
