Product notes
Jabsco 18660-0121 Marine Water Puppy

The Jabsco Water Puppy has a bronze housing and a black finish. The listing includes the Jabsco Water Puppy as the bundled component, and the item display weight is about 6 pounds. That combination makes it a heavier, more solid pump compared with a compact plastic unit. Choose this pump when you want a metal-bodied marine pump for bilge or sump duty. The trade-off is the condition: it is listed as new other, not new, so the item is not described as a sealed retail unit. If you prefer a heavier pump, this is the one to pick.
1100GPH Marine Pump

The 1100GPH Marine Pump has a heat-resistant ABS housing and a snap-lock strainer base for easy cleaning. It also has universal mounting holes, making installation simpler in a variety of locations. As a compact pump, it fits easily into tight spaces. Choose this pump when you want a compact unit for bilge or sump duty. The limitation is the ABS housing, which is different from the bronze body on the Jabsco. If you need a pump with a metal housing, this compact ABS model is not that.
Final choice by use case
For a flexible impeller pump with a bronze housing, the Jabsco Water Puppy is the pick. For a compact submersible pump with a snap-lock strainer base, the 1100GPH Marine Pump is the straightforward choice. Your decision comes down to whether you prefer a heavier metal-bodied pump or a lighter compact unit.
