Johnson L750GPH LOW BOY Bilge Pump - 12v
Choose the 12v L750GPH LOW BOY Bilge Pump for a marine bilge installation that matches its hose size, capacity and electrical requirements. Product 183890 uses a 3/4” connection; the detailed flow figures below let you compare the pump at the stated test conditions.
Flow reduces as pumping head increases. Compare the zero-head figure with the rated output at the listed lift rather than treating the model name as the delivered flow at every installation. The test voltage is also relevant when comparing pump capacities.
The low-profile removable-cartridge design is intended for confined bilges beneath inboard or stern-drive engines. Dura-Port discharge ports help reduce stress cracking associated with overtightened hose clamps.
Check the 12v supply, specified fuse and current draw together when selecting the electrical arrangement. Match the discharge hose to the 3/4” connection and leave room to service the pump after it is fitted.
For comparison, capacity Zero Head(13.6v/27v): 50Lpm - 800GPH, while capacity at 3ft (0.9m) Head (13.6v/27v): 44Lpm - 700GPH. These two operating points show why the hose route and lift need to be considered with the capacity. Use the rated point relevant to the installation when narrowing the pump choice.
Choosing and using this product
Compare the package contents with the complete installation you are planning. Pump-only listings and kits can differ in switches, fittings and hoses. Listing the required components before ordering helps you select the appropriate package and avoids treating an illustrated accessory as an included part.
For a service part, identify the existing pump model before ordering. A motor cartridge, switch, strainer or valve renews only its stated part of the assembly. Check adjacent hoses and connections at the same time so an unrelated problem is not mistaken for a failed replacement component.
