Ok to run hood with no vent tubes?

Both of the tubes that connect to the hood on my superjet are missing? Do not having the tubes have any disadvantages?

The tubes are there to direct water intrusion down to the bottom of the hull

I never realized that it was for that, just thought it was for air. Ill steal some of my square nose for now.

Yeah they also bring in air of course, it just helps to give the water a path away from the engine and e-box and into the bilge area. I used to run without the tubes and some of those frogskin intake screens there, just ended up letting more water get on the engine. A lot of people cut em off because it's easier to get the hood on/off.

On a/m hoods I like to have at least 4 air/water baffle tubes, one on each side of the carburetors and long enough to keep water out of flame arrestors, then two at the front
