Is this really important?

[SeaEsta-12]

Ok.....so this is the first boat that I have owned with a DuoProp, and I am going to be changing my props this weekend from aftermarket, to the standard F4 series from VP.
Someone had mentioned to make sure that I have my prop timing correct when installing the two props.
What exactly does he mean by that? I was unaware that there was an actual rotation alignment on DP set ups.
Any input?

It does help with cavitation burn a bit on the props on the old DP drives. Install forward prop straight down, install aft prop opposite (straight up)

I like the term "clocking". It certainly cannot hurt and is "free", and I am convinced it makes a difference.
