the vents on the side tend to collect rainwater because Attwood (who makes most of the low end air boxes) didnt care if the rain entered the bilge
the vents under the aft transom cover are actually better from a water ingress point of view.
the blower is to move air until the engine is fired up. there is a low hose from bottom of bilge to the blower, then a hose to the vent. this will pull all the fuel fumes that have settled to the bottom of the bilge and expel them. that is the science to keep your boat from blowing up.
the engine will move 3x the air that the blowers can.
dont over-think it.
use the aft blower vents you have, hook up a blower to one, and add a bit of duct to the lowest point in the bilge.
