Don't have a shot of them but they are round bronze plates about six inches in diameter that are dished out a bit like the top of a tennis ball. The plates are perforated with holes.

There are eleven holes in the bottom of our boat. Eight of them are intakes and they all have the perforated bronze plates over them. Three are discharges and so have no perforated plate over them.
