1995 Seadoo GTX Vents

My question is what are these vents for and what prevents water intrusion when backing ski off the trailer?

I don’t think they are open on the inside. Battery vent connects to one

There is an internal baffle that keeps water out. They are vents, you engine needs oxygen to run.
