Jabsco 37245 Series Quiet Flush Electric Toilet, Seawater

Overview

The Jabsco 37245 Series is a Quiet Flush electric marine toilet for boats that use sea or lake water as the rinse supply. It pairs a white vitreous china bowl with a remote Par-Max 3 self-priming rinse pump, a multi-function flush control, and a macerator discharge pump for moving waste to a holding tank or correctly installed discharge system.

This series covers compact and regular bowl layouts in 12 VDC and 24 VDC versions. The control allows a normal flush, separate rinse-water fill, and separate bowl evacuation, so the user can manage bowl level at the dock, at anchor, or underway in rough water. Water use is listed at 1 to 2 quarts per flush, with 3/4 in (19 mm) rinse plumbing and a 1 in (25 mm) discharge hose connection.

Key features

• Quiet Flush operation suits heads located near cabins or sleeping areas, where a standard electric toilet can be intrusive.
• Single large flush button activates rinse water and the macerator discharge pump together for normal use.
• Separate rocker control lets the user raise or lower the bowl water level without running a full flush cycle.
• Remote Par-Max 3 self-priming rinse pump draws sea or lake water from the vessel intake circuit.
• White vitreous china bowl is available in compact and regular sizes to match the available head space.
• Regular bowl versions include options with a soft close seat and lid.
• Electrical versions match either 12 VDC or 24 VDC systems, with 12 VDC models drawing 10 amps and 24 VDC models drawing 5 amps.
• High capacity macerator and discharge pump move waste through a 1 in (25 mm) discharge hose.

Variants

The range varies by bowl size, DC voltage, and seat/lid style. Compact versions reduce the footprint in tighter head compartments, while regular bowl versions give a more household-size seating position.

The 12 VDC versions suit common small craft battery systems, and the 24 VDC versions suit larger vessels with 24 volt DC service. Soft close seat/lid variants are limited to the regular bowl configuration, while the seawater rinse arrangement, flush control layout, Par-Max 3 rinse pump, white china bowl, and macerator discharge system remain common across the 37245 Series.

Installation and plumbing

Plan the install around the intake, rinse pump, discharge hose, and switch panel, not just the toilet footprint. The Par-Max pump is remote mounted and should be kept close to the toilet where practical; it can be mounted above the waterline, with the Pumpgard strainer placed in an accessible section of the inlet plumbing for inspection and cleaning.

Use 3/4 in (19 mm) hose that will not collapse or kink on the rinse side, and reinforced 1 in (25 mm) sanitation hose on the discharge side. Install a correctly positioned vented loop when the toilet or overboard discharge plumbing is below the vessel waterline, and keep plumbing runs as direct as possible to reduce standing waste and blockage points. Maximum discharge head is 4 ft (1.3 m) without a notable drop in pump performance.

Electrical fit

The toilet should be wired on an independent circuit with marine-grade stranded copper wire and a correctly sized fuse or breaker. The 12 VDC versions call for a 25 amp fuse, and the 24 VDC versions call for a 15 amp fuse; wire size depends on the total length of the positive and return run.

For customers replacing an older electric head, the voltage and hose sizes are the first checks before purchase. The switch panel also needs a convenient bulkhead location with access for wires to the waste pump, rinse pump, and power source.

Use cases on board

This series is a practical match for cruising sailboats, powerboats, and fishing boats that already use a raw-water toilet intake and want a quieter electric flush than a basic macerating head. The compact bowl helps in narrow heads or secondary cabins, while the regular bowl makes sense where comfort and space matter more than footprint.

Maintenance and care

Routine care is simple: clean the bowl with mild non-abrasive cleaners and avoid strongly aromatic cleaners or concentrated degreasers, which can affect pump seals. The Pumpgard strainer should stay accessible so debris from the intake water can be checked and cleared before it restricts rinse flow.
