[OMC-Boats] cowling venting

kind of inexperienced with boat i/o motors. here's something i
don't get.......why no venting in the cowling? i happen to have a
Deluxe, but i think it's the same story with other boats as well.

  - You are supposed to vent the fumes out with a blower before
starting.
- the top of the carb has an air cleaner intake just like a car
(although small)

yet my particular cowling seals up pretty tight and seems like it's
designed to not let any air get in. it does have a smaller grill in
the back of the engine compartment, but minimal. So why aren't
cowlings (or atleast mine) vented like crazy with air grills all over
the place? it just seems like it would A) make the engine run better
by providing more available fresh air intake, B) make the engine run
even cooler with air flow taking away some of the heat , and C) make
it easier for the accumulating fumes to get out of the cowling without
having to rely on the blower.

I have a perfect spot right on the front of the cowling for a nice big
chrome vent, but i don't want to be cutting any holes without knowing
for sure first.
