Where can I purchase these? They dont have to be exact because I'm going to replace all 6.
Thanks

Is that really a Nortech with WalMart Vents

I would upgrade them, some of the ones in the below link should have the same size/screw pattern.

Well you can try either of these vendors.

I'm pretty sure those look like vents I've seen at Dana Marine.

We can machine you some of these..
they are polished stainless. made to fit right in the same spot

EMI is the only company that I have found that makes them the exact same size as the Attwood vents, unless you go with custom made like BYC offers.

it says they dont fit the blower vent covers, kind of defeats the purpose.

Went with the upgraded aluminum to match the paint. Thanks for all the suggestions. Will be here Friday. Thanks Eddie Marine and for all the suggestions.

That would be blower vent collars. All you need to do is is use a few zip ties to hold the vent tube in place near the vent. Mine already have the Attwood collars and they work.

you are correct, just wondered why they wouldnt incorporate such an important safety consideration. Not much point running the blowers if the "potential fumes" are not being properly exhausted.
