One drive is chain driven, the other is gear driven (to change rotation). The gear drive box is less efficient than the chain drive and will extract more power but I wouldn't think it would 15%. Do you know which side the gear drive box is on?

What horsepower are you making?

Hold on, let’s back up a bit......
I am talking about the ASD8 drives, not the transmissions.
So are you saying the counter rotation is accomplished in the transmissions rather than the drives?
I am not well versed on the ASD8 but assumed it was similar to the ASD7 which uses gears to reverse rotation on one drive and a chain/sprocket combo on the other drive.

Ok, well excuse my ignorance and I learned something here.
If you have #6 props I have a spare set if you’d like to try them.
They are considerably smaller than what you are running though.
