This pump arrived on Thursday and I was looking forward to using it as the transport mechanism for freshly mixed saltwater during my weekly
PWC. It is advertised as being able to run both in and out of water. However, I had zero luck getting it to run out of the water. Once fully submerged, it pumped like a champ.
So, if you're planning on running this pump (or presumably any of the pumps in this product line) in a submerged environment: 10/10.
If you want it as an external/non-submerged pump: 0/10.
