If you're shopping for a marine pump, the first practical question is how much water you need to move and how quickly. For a boat bilge, a fountain, or a runabout, a 12V submersible pump is a common answer. The decision gets interesting when two listings show up for the same pump at the same price, both from The Perfect Part.
Quick verdict
Both listings describe the same new pump from The Perfect Part. There's no feature gap between them, so the real choice is which listing you prefer to use, not which pump performs better.

Product notes
1100GPH 12V Electric Marine Submersible Bilge Sump Water Pump For Boat 3/4" Hose

This listing is a good fit if your boat or aquarium setup already uses a 12V electrical system and a 3/4-inch hose line. It comes as a new unit from The Perfect Part, so you know exactly what you're looking at before you decide. The limitation is also visible in the title: the pump is specified for a 3/4-inch hose connection, so it's intended for that size. If you're after a straightforward 12V submersible pump for a bilge, this one gives you the core specs without extra complexity.
1100GPH 12V Electric Marine Submersible Bilge Sump Water Pump For Boat 3/4" Hose

The second version of the listing offers the same pump, the same brand, and the same 12V electric operation. The casing details are the same as the other listing, so there's no visual difference to weigh. The one limitation is that there's no feature in this listing that sets it apart from the first; you're choosing between two identical descriptions. If you need a 12V marine pump for a fishing boat or runabout, this listing works just as well, but it won't give you anything extra in specs.
Final choice by use case
Because both listings are identical in listed specs, choose the one that feels right for you. The only step is to make sure the listed details line up with your water-removal job before you buy.
