IIRC Porsche even had a “recall” to stick another page in the owner’s manual stating that it was the customer’s responsibility to keep the drains clear. Best bet is to remove entirely the little grommet in the hole in the bottom of the cowl. Can’t remember if later models had that same pinchy grommet thing in the drain hole.

Ding, ding, ding!



I've got couple of videos queued up on YT to see if there are any with good visuals to make it easier for me to just go right to the spots that need checking/cleaning. Hopefully, those grommets are easy to remove.
