Can anyone identify the flat light brown growth that is over the intake of the sd20 sail drive?

The regular barnacles I recognize. But the brown stuff is like a sheet of hardened tape. Why would it span the intake like that?

What options are there to defend against this?

I used to get this on my outdrive when I had an Express Cruiser. I had more problems with barnacles clogging the intake than this stuff. I can't identify the species of marine life. Dive on the saildrive once a week with a brush and have at it for a few minutes. It will prevent the growth from occurring.
