Ive found 2 of these while rummaging through the old fish tank stuff from when my mom had a 75 gallon and I found 2 power heads they work fine and are still intact but im wondering if they are submersible... Im too scared to figure out the hard way hehe :)

I think all powerheads are submersible, at least the 4-5 types I've used over the years have been. If you're not sure, try them out in a bucket of water.
