Choose the Correct Attwood Products
When replacing an existing Attwood product, compare the model or part number whenever it is available. Also confirm the mounting dimensions, electrical voltage and current requirements, hose or wiring connections, installation space, and included hardware.
For bilge systems, verify the required flow rate, hose diameter, discharge routing, wiring, fuse protection, and whether automatic operation requires a separate float switch. For seating systems, confirm the pedestal series, post diameter, mounting pattern, height, and compatibility among the seat mount, post, and base.

Attwood Marine Parts FAQs
How do I choose the correct Attwood bilge pump capacity?
Bilge-pump capacity is measured in gallons per hour. Consider the boat’s size, bilge volume, intended pump location, hose length and routing, and whether the pump will serve as the primary or backup system. Actual installed output can be lower than the advertised rating because of discharge height and plumbing resistance.
What is the difference between a manual and automatic bilge pump?
A manual bilge pump is operated through a separate switch or control. An automatic pump uses an integrated water sensor or a separate float switch to activate when water rises. Review the individual pump’s design before determining whether an additional float switch is required.
Why does my bilge pump run continuously?
Continuous operation can be caused by a stuck or incorrectly mounted float switch, debris, wiring problems, excessive water entering the bilge, or a problem with an integrated sensor. Inspect the complete system before assuming the pump itself has failed.
How do I choose the correct Attwood seat pedestal components?
Confirm the pedestal series, post diameter, base type, mounting pattern, desired height, and compatibility between the seat mount, post, and deck base. Components from different pedestal systems may look similar without being interchangeable.
How do I select the correct marine battery box?
Measure the battery’s length, width, and height, including the terminals, and compare those measurements with the box’s interior dimensions. Also verify the installation space, cable routing, ventilation needs, and supplied hold-down system.
What should I check when replacing boat navigation lights?
Confirm the required light type, visibility arc, visibility distance, mounting position, boat length, voltage, wiring, and applicable navigation-light requirements. A replacement light should be suitable for the same function and installation location as the original.
