Mine are the same way. Left hand rotation drive is pretty dark.

Now that you say that, it was my left hand turning drive as well. Wonder if I should switch them while there off to "spread the wealth"?

Interesting observations on darker oil in LH drives. Darker usually means hotter.

Now, it's common knowledge that Bravos can turn either way because they have symmetrical gear patterns but that necessarily doesn't mean that the oil is flowing properly turning opposite directions...could there be less cooling (foaming, etc.) when turning LH versus RH?

It's also the drive which I use the least. I spend much of my time running on one motor when not on plane. RH has the PS pump.

Hey Scott, so this will probably be a dumb question but is the rotation based on looking at the drive from behind or from the front? It was my starboard drive that was darker, & i assumed i was turning the props out, but i will verify. The port drive was nice & green.

I have never had a TRS drive, but on other drives a bad bellows can sink the whole boat. A leaking bellows is not something to be taken lightly

Looking at the props from the rear. LH is the one spinning counter clockwise.

Thanks, thats how i was looking at things.
