Works for more than Boats!
Worked like a Charm!! We used this as an access port for a sewage lift station. We will most likely order lore of these in the future whenever we install lift stations as a means of access for inspection & service.

Quality Deck Plate
Well engineered and with build quality to match. These deck plates are easy to install and seal very well.

Questions
Can you use this for a fresh potable water marine tank inspection port?
Yes. I've installed two on stainless steel tanks, to replace solid stainless tanks I had to unscrew to inspect. Had to screw a few new holes in the flanges of the new ports, but not a big deal.
