My transmission fluid is milky and a bit yellowish in color. I think the coloring is from moisture as I am told?? Anyone else have this or know what caused it? Could it just be from condensation? The boat is new to me so I don't know when it was changed last.
It is a 2006 x45

Sounds like water to me, I would go ahead and change out the transmission oil, iirc its 15w40, and recheck it.

Any milk in the bilge? I would change as suggested above, run it and recheck.
In 35+ years of MC ownership, I've yet to see condensation cause milky oil in the trans.

I would change it, run it for a minute, then change it again to make sure as much moisture as possible is flushed out.

It will take several changes to clear out all of the water....if isn't because of a leak.

Check out your transmission cooler for leaks.

How do ya check it for leaks. I am sure this is what it is. I have a saltwater special so I believe it is antifreeze in the oil as I mixes a bit of antifreeze with new oil and it is a match to the oil! Do ya just take the transmission cooler out? Is it simple just undo all connections and pressure test for leaks?

No luck. Took the transmission cooler off and checked for leaks. It seems ok. The tranny oil is greenish so I think it is antifreeze as my antifreeze is low and I just topped it off. My tranny cooler is 100 percent fresh water cooled. Where could antifreeze get into the transmission. Please help before I blow this thing up! :)

I'd warm it up - Use vacuum tank to remove all of it - put sample in jar and let it settle out to see if in fact it is water.
Has to be getting in somehow if it is water.
