The 5 Best Stainless Boat fittings (2023 reviews)

The attwood stainless steel is long-lasting, rigid and fits well with your regular usage like a dream. This thru hull looks to be very well made, and hasn't rusted at all. It has full length thread for thick hulls and easy tightening. It has a port or a hole that gets hooked up to a hose to drain water out of a boat. It looks pretty clean on the outside of the hull as well. The discharge point should be well above the waterline of your boat so it should not be plugged.

This should be used for discharge from a bilge pump. It comes with the lock nut but you will have to get some silicone adhesive that is rated for above/below water line for through hull fittings.
