Seachoice 12 GPM Marine Macerator Pump – 12V, 12A (17888)
A sealed, ignition-protected macerator pump built for reliable holding tank discharge in marine environments. The 316 stainless-steel four-blade cutter handles waste efficiently with minimal clogging, while the sealed motor and soft rubber vibration mounts keep operation quiet and corrosion-resistant over the long term. A patent-pending universal mounting bracket simplifies installation on most existing pump footprints.
Key Features
- 12 GPM flow rate: High-volume discharge clears holding tanks quickly and efficiently.
- 316 stainless-steel four-blade cutter: Macerates waste thoroughly to reduce clog risk and ensure consistent pump performance.
- Sealed motor: Fully sealed for superior corrosion resistance in salt water and high-humidity marine environments.
- Ignition-protected: Complies with ISO ignition protection standards — safe for installation in engine compartments and enclosed spaces where fuel vapour may be present.
- Dry-run safe: Can operate safely if the water supply is temporarily interrupted — no damage from momentary dry running.
- Self-priming to 6 ft (1.8 m): Primes automatically without manual intervention, even when mounted above the waterline.
- Quiet operation: Soft rubber mounts absorb vibration and reduce noise during pump cycles.
- Easy unclogging: Accessible knob on the pump body allows quick manual clearing of blockages without disassembly.
- Universal mounting bracket: Patent-pending bracket fits most standard pump footprints for straightforward retrofits.

Parts Desk Insights
This pump is the right call for customers replacing an existing macerator on a holding tank discharge system or adding pump-out capability to a new sanitation build. The universal mounting bracket is a genuine time-saver on retrofits — it eliminates the need to drill new mounting holes in most cases. The ignition-protection rating matters if the pump is going anywhere near the engine compartment or a fuel tank; confirm this with the customer before recommending a non-rated alternative. The easy-access unclogging knob is worth highlighting to customers who’ve dealt with clogged macerators before — it’s a real differentiator over pumps that require full disassembly to clear a blockage. For customers comparing options, also show the Jabsco 18590-2092 and Johnson Pump 12V macerator side by side on flow rate and mounting.
