[Public-list] Cowl vents

[John Birch]

Hi Ed,

The screw vents you are speaking of were made by Fico who have since dropped 
the screw fitted type production line in favour of the inferior, in my 
opinion, snap on type. I can suggest two solutions 1) shop the used boat 
part chandleries for another one, Or 2) buy a new snap on, take off the snap 
on base and have a bronze threaded male part manufactured at your local 
machine shop and affix it to the cowl.

If you are successful finding an off the shelf screw in replacement, please 
let us all know as I'm sure many of us might want to replace some with the 
like design.

Best of luck.

Cheers,
John
