Johnson Pump Marine Pumps and Water-System Equipment
Johnson Pump Marine manufactures bilge pumps, automatic switches, engine-cooling pumps, flexible impellers, washdown systems, marine toilets, and related equipment for recreational and commercial boats. Its product range supports both onboard water management and marine-engine cooling applications.
Selecting the correct pump requires more than matching the general product type. Compare voltage, capacity, hose connections, mounting space, operating conditions, existing part numbers, and included components before ordering.

Johnson Bilge Pumps
Bilge pumps remove accumulated water from the lowest areas of a boat. The appropriate pump depends on the vessel, bilge layout, required capacity, discharge-hose size, vertical lift, electrical system, and whether automatic operation is needed.
A pump’s advertised GPH capacity is generally measured under specified test conditions. Actual output can decrease as discharge height, hose length, bends, restrictions, and system resistance increase.
Johnson Pump Cartridge Bilge Pump
A cartridge-style bilge-pump series designed so the motor cartridge can be accessed for compatible maintenance or replacement while the pump housing remains installed.
Johnson Pump ProLine Bilge Pump
A submersible bilge-pump option for compatible recreational and commercial marine installations. Select the appropriate voltage, capacity, and hose connection.
Johnson Pump First Mate 400 GPH Bilge Pump
A compact 400 GPH bilge pump for compatible smaller-boat and limited-space installations.
Johnson Automatic Bilge-Pump Switches
A standard bilge pump requires a separate switch or control system for automatic operation. Switches should be mounted according to their instructions and positioned where they can detect bilge water without interference from hoses, wiring, debris, or surrounding equipment.
Confirm voltage, amperage capacity, wiring requirements, pump compatibility, and mounting space before replacing or adding a switch.
Johnson Ultima Automatic Bilge-Pump Switch
An electronic automatic switch for operating a compatible bilge pump when water reaches the switch’s activation area.
Johnson Pump Automatic Bilge-Pump Float Switch
A mechanical float-style switch for adding automatic operation to a compatible bilge-pump installation.
Johnson Pump Electro-Magnetic Bilge-Pump Switch
An electro-magnetic automatic-switch option for compatible Johnson bilge-pump systems. Verify the electrical rating and installation requirements.
Johnson Pump Engine Cooling and Flexible Impellers
Flexible-impeller pumps circulate raw water through compatible marine-engine cooling systems. The rotating impeller is a service component that can wear, take a set during storage, lose vanes, or become damaged if the pump runs without adequate water.
Replacement pumps and impellers should be identified by the engine application, serial number, existing pump model, pump number, impeller dimensions, shaft style, and original part number. A visually similar impeller is not proof of compatibility.
Johnson Pump F5 MC97 Impeller Kit
An MC97 flexible-impeller service kit for compatible Johnson F5 pump applications. Confirm the existing pump model, impeller dimensions, and shaft connection before ordering.
Johnson Pump F6B-9 Engine-Cooling Pump – Indmar 68-5001
A Johnson Pump F6B-9 engine-cooling pump identified as genuine Indmar part 68-5001. Verify the Indmar engine application and existing pump number before replacement.
Johnson Pump and Volvo Penta Engine Cooling
Johnson Pump Marine manufactures original-equipment engine-cooling pumps used in select Volvo Penta applications. This OEM relationship makes Johnson Pump an important source for compatible raw-water pumps, flexible impellers, and service components.
The Johnson Pump name on an existing pump does not mean that every Johnson replacement fits every Volvo Penta engine. Confirm compatibility using the Volvo Penta engine model, serial number, original Volvo Penta part number, Johnson Pump model, or number shown on the existing pump.
Volvo Penta Water Pumps and Impellers
Shop complete water pumps, replacement impellers, and cooling-system service components for compatible Volvo Penta marine engines and sterndrives.
Johnson Aqua Jet Washdown Pumps
Washdown pumps supply pressurized water for rinsing decks, fishing areas, anchors, and other suitable surfaces. Compare voltage, rated flow, pressure, hose connections, included components, electrical protection, and available mounting space.
A washdown pump is not automatically suitable for drinking-water service. Use each pump only for the applications and liquids approved by its instructions.

A packaged Aqua Jet washdown solution for compatible boat installations. Review the product listing to confirm flow, voltage, connections, and included accessories.
Johnson Aqua Jet 5.2 GPM Washdown Pump
A 5.2 GPM washdown pump for compatible marine rinsing systems. Confirm voltage, pressure, plumbing, and electrical requirements before installation.
Johnson AquaT Marine Toilets
Johnson AquaT toilets include manual and electric options for compatible onboard sanitation systems. Before replacing a marine toilet, compare the footprint, mounting pattern, bowl dimensions, water supply, discharge connection, voltage, wiring, and available service clearance.
Johnson Pump AquaT Silent Electric Marine Toilet
An electrically operated AquaT marine toilet for compatible onboard sanitation installations. Confirm voltage, plumbing, mounting, and discharge requirements.
Johnson AquaT Compact Manual Marine Toilet
A compact manually operated marine toilet for boats where space is limited or an electric flushing system is not required.
Johnson Pump FAQs
How do I choose the correct bilge-pump capacity?
Consider the boat, bilge layout, discharge height, hose size, system resistance, electrical capacity, and manufacturer guidance. Advertised GPH and actual installed flow may differ.
What is a cartridge bilge pump?
A cartridge pump allows the motor and impeller cartridge to be accessed while the compatible housing and discharge plumbing remain installed, simplifying certain maintenance and replacement tasks.
Does every Johnson bilge pump operate automatically?
No. Some pumps require a separate compatible float or electronic switch, while other models may include automatic sensing or a preconfigured switch. Review the individual listing carefully.
How do I identify the correct Johnson Pump impeller?
Use the existing pump model, Johnson part number, engine application, impeller dimensions, shaft connection, and original part number. Do not identify an impeller by diameter or appearance alone.
Does Johnson Pump manufacture Volvo Penta water pumps?
Johnson Pump manufactures original-equipment engine-cooling pumps used in select Volvo Penta applications. Compatibility must still be confirmed for the exact Volvo Penta engine, serial number, and pump number.
What is the difference between a washdown pump and a freshwater pump?
A washdown pump supplies pressurized water for rinsing suitable surfaces. A freshwater pump supplies water to compatible onboard fixtures. Use each pump only for its approved service.
Should I choose a manual or electric marine toilet?
A manual toilet operates without an electric flushing motor, while an electric model requires compatible power and wiring. Compare space, plumbing, electrical capacity, and intended use.
