Quick Verdict
When you're comparing gear in the marine pumps plumbing sanitation space, you're usually solving one of two problems: getting water out of the boat or routing water through the hull. These two parts sit at opposite ends of that job. The 1100 GPH Submersible Bilge Pump 12V is the active solution, moving up to 1100 gallons per hour with a 12V motor. The Marine/Boat 90 Degree Thru Hull Plumbing Fitting is the passive connection, giving a 3/4-inch hose a clean right-angle exit through the hull. Your call should follow the job: pump if water is pooling, fitting if the hose path needs an exit. This comparison keeps the choice simple: either you're moving water or you're plumbing its path.

Where Each Product Wins
- 1100 GPH Submersible Bilge Pump 12V wins when the boat is taking on water and you need a pump that can sit in the bilge, draw about 8.5A, and push water through a 29mm (1-1/8") outlet. Its water-cooled motor can run briefly without water, and the removable filter makes cleanup straightforward.
- Marine/Boat 90 Degree Thru Hull Fitting wins when the rest of your plumbing is already set and you simply need a hose connection through the hull. The UV- and chemical-resistant polypropylene body and finished head suit a marine environment, and the single pass-around nut helps you tighten it.
1100 GPH Submersible Bilge Pump 12V Marine Boat Electric Water Pump 29mm Outlet
The 1100 GPH Submersible Bilge Pump is a compact electric pump for boats, seaplanes, houseboats, and motor homes. It flows 1100 GPH on 12V DC, draws roughly 8.5A, and has an ABS sealed housing, stainless steel shaft, and thermoplastic body. The water-cooled motor can run briefly without water, and the pump doesn't need to be fully submerged to pick up water, which can be useful if the bilge water level is low. If you need active bilge-water removal, this is the pump to reach for. The catch: batteries and wiring accessories are not included, so you'll need to supply 12V power and connect the wires yourself.
Marine/Boat 90 Degree Thru Hull Plumbing Fitting for 3/4 Inch Hose
The Marine/Boat 90 Degree Thru Hull Fitting is a right-angle hose connection made from UV- and chemical-resistant virgin polypropylene and sized for a 3/4-inch hose. It has a finished head and a single pass-around nut, and the carded pack keeps everything together. This fitting earns its place when your plumbing run needs a neat 90-degree exit through the hull rather than another pump. The limitation is that it is a fitting, not a pump, so it won't move water on its own. If the job is simply routing hose through the hull, this is the part to get.
Final Choice by Use Case
If you need to actively pump water out of the bilge, choose the 1100 GPH Submersible Bilge Pump at USD 9.99. It brings the 29mm outlet and water-cooled motor that make sense for active removal. If the pump is already in place and you just need a UV-resistant right-angle exit for 3/4-inch hose, choose the Marine/Boat 90 Degree Thru Hull Fitting at USD 8.99. Between them, that's a $1.00 spread, and the part that matches your plumbing job is the one worth buying.
