Jabsco 12V Water Puppy Flexible Impeller Pump – 18660-0121
The Jabsco 12V Water Puppy Pump is a compact, reliable flexible impeller pump designed for efficient fluid transfer in marine, RV, and light commercial applications. Known for its dependable performance and quiet operation, the Water Puppy is ideal for washdown systems, freshwater transfer, livewell circulation, and general-purpose pumping where self-priming capability is essential.
Built with Jabsco’s proven pump technology, this 12-volt DC pump delivers consistent flow while withstanding demanding marine environments.
Flexible Impeller Pump Technology
The flexible impeller design allows the Water Puppy to self-prime and handle intermittent dry running, making it ideal for applications where suction lift and reliable priming are required.
12V DC Marine Power
Operating on 12-volt DC power, this pump integrates easily with most onboard electrical systems, making it perfect for boats, RVs, trailers, and mobile utility setups.
Compact & Easy to Install
The compact footprint allows installation in tight engine rooms or compartments. Standard hose connections and straightforward wiring simplify setup and replacement.
Marine-Grade Construction
Manufactured with corrosion-resistant materials, the Water Puppy is designed to handle moisture, vibration, and frequent use. Jabsco’s reputation for quality ensures long service life and dependable operation.
In the Box: 18660-0121
-
(1) Jabsco Water Puppy Pump: 12V DC unit with a solid bronze pump head.
-
(1) Neoprene Impeller: Pre-installed (designed for water-based applications).
-
(2) Port Adapters: 1/2" NPT to 3/4" Male Garden Hose.
-
(1) Installation Manual: Including wiring guides and service parts breakdown.
Key Features & Benefits
1. Robust Bronze Construction
Unlike plastic pumps, the Water Puppy features a high-quality bronze body and a stainless steel shaft.6 This prevents the threads from stripping and ensures the pump head can withstand the high pressures of washdown applications without cracking.
2. Excellent Self-Priming
The flexible impeller design allows the pump to create a vacuum even when dry. It can lift water up to 4 feet (1.2m) vertically, meaning you can mount the pump in a dry location above the bilge or waterline for easier maintenance.
3. Debris Tolerance
The flexible vanes of the impeller can pass small solids (like sand or fish scales) that would jam a centrifugal or diaphragm pump. This makes it an ideal choice for bilge pumping in real-world conditions.
4. Versatile Ports
The pump head is designed to accommodate multiple connection types:
-
Internal: 1/2" Female NPT (standard pipe thread).
-
External: 1" Hose Barb (for large diameter bilge hose).
-
Included Adapters: 3/4" Male Garden Hose (for standard washdown hoses).

Pro-Tip for Maintenance:
"The 18660-0121 comes with a Neoprene impeller, which is perfect for water but will swell and fail if it touches oil or diesel.14 If you are using this pump for a bilge that often has engine oil in it, you should swap the impeller for a Nitrile (oil-resistant) version (Jabsco Part #6303-0003)."
