SEAFLO 12V Marine Toilet Conversion Kit — Electric Macerator 5.0 GPM, Stainless Chopper, Fits Compact & Regular Heads

Convert a manual marine toilet to a reliable 12V electric flush with SEAFLO’s self-priming macerator pump, delivering 5.0 GPM and a durable stainless steel chopper for smoother waste discharge.

Upgrade your boat’s head without replacing the entire toilet: the SEAFLO SFMTP1-02 conversion kit replaces manual pump hardware with an electric macerator and rinse system designed to fit both compact and regular marine heads. Built for corrosion resistance and onboard convenience, this kit simplifies daily use, reduces clogs, and supports flexible plumbing arrangements above or below the waterline.

How does the conversion kit improve flushing performance?

The SEAFLO conversion replaces manual action with a 12V electric macerator and rinse pump that provides consistent flow and stronger bowl rinse. The stainless steel chopper plate reduces large solids before discharge, lowering the chance of blockages and improving overall reliability.

• 5.0 GPM (18.9 LPM) flow for strong rinse and evacuation
• Stainless steel chopper plate for efficient maceration
• Self-priming up to 2 ft for straightforward installs
• Electric operation removes the need for repetitive manual pumping

Can I install this kit on different toilet layouts and plumbing routes?

The unit’s reversible rotation and compact footprint allow left- or right-hand installations and fitment in tight compartments. It supports varied discharge routing, including high-head and through-hull configurations, so it adapts to many vessel plumbing setups without extensive rework.

• Adjustable rotation for left or right installations
• Discharge up to 6 ft over an anti-siphon loop for high head routing
• Suitable for through-hull discharge down to 3 ft below waterline
• Compact dimensions (11.8" x 7.5" x 4.7") for space-limited heads

What are the electrical and plumbing requirements I should know?

This conversion runs on 12V DC and draws up to 24A during operation, so a properly rated fuse and wiring are essential for safe performance. Standard hose sizes accommodate the unit, and simple mechanical connections make it accessible for competent DIYers or marine technicians.

• 12V DC operation, 24A maximum current draw
• 3/4" inlet and 1.5" discharge hose connections
• Self-priming capability supports above-water installations up to 2 ft
• Compact mounting reduces the need for custom brackets

The SFMTP1-02 conversion kit is backed by SEAFLO’s 4-year warranty, reflecting component durability and manufacturer confidence. Stainless-steel chopping components and marine-grade materials help extend service life in harsh boatboard environments.

• 4-year warranty for long-term support
• Stainless steel chopper for corrosion resistance and strength
• Designed for frequent onboard use and demanding discharge cycles
