Hey folks. I purchased all 3 new livewell thru hull fittings for my bassboat today and when I got home I noticed they said "not for below water line". These will obviously be below the waterline. I'm wondering if it really matters or if that's a "lawyer disclaimer". My boat is trailered and not slipped so it wont stay in all the time. One of them is a Perko and the other 2 are attwood. I'd be putting them in with 5200. Should I run em or return them for ones rated for below water line? What's the difference. Thanks!
