On my 84 westy my 'flu' (is that the right term?) is covered completely with a
sort of hard rubber black cover with one philips screw in the middle (so no
water can get in, I guess).
I understand that when I use my stove (I haven't ever used it so far) I need
to remove this, and the other westy's I've seen have a cover with vents in it
(I think...).

What's the deal?

Peace,
