GPH stands for gallons per hour—the flow rate a pump can move. On this page, you’ll see options from compact aeration kits (around a few hundred GPH) up to high-flow pumps (1,000–2,000+ GPH). Picking a flow rate depends on your tank size and how much water turnover you prefer.

• Smaller tanks: Lower-flow pumps can be easier to control.
• Larger or heavily stocked tanks: Higher GPH can help move more fresh water.
• Fine-tuning: Kits with adjustable spray heads let you dial in flow.
• Mounting and space: Dual-mount and vertical versions are available for tighter installs.
• Power: Most marine pumps here are 12V, with some 24V options.

Checking each product’s specifications and your plumbing size can help you find a good match for your setup.

Several options listed here are designed for both freshwater and saltwater use. Product titles call out features like “fresh/saltwater use” and “corrosion-resistant,” which can be helpful if you boat in coastal areas.

• Look for: Descriptions that explicitly mention saltwater compatibility.
• Materials: Corrosion-resistant construction is common in marine-rated pumps.
• Styles: Submersible livewell/baitwell pumps, dual-mount units, and aeration kits are available.
• Flow rates: You’ll find a range from compact aerators to 1,600–2,000+ GPH pumps.
• Power: Most options are 12V DC; confirm voltage in the specs.

Review each item’s details to confirm suitability for your water type and installation. Conditions and maintenance habits can influence longevity and performance.

Both are marine pumps, but they serve different jobs. The assortment here includes bilge pumps, livewell/baitwell pumps, and aerators.

• Bilge pumps: Designed to move unwanted water out of the boat’s bilge. Many are submersible; some work with automatic float switches for hands-off operation.
• Livewell/Baitwell pumps: Built to circulate water into a tank for bait or catch. They’re typically rated by GPH and may feature removable cartridge motors or adjustable spray heads.
• Aerators: Portable or kit-based units that add oxygen to bait buckets or tanks, including rechargeable floating options.

Choosing between them depends on the task—dewatering vs. circulating/aerating water—and the power source and flow rate you prefer.

You’ll find a few portable choices for on-the-go bait care. These can be handy for dock, kayak, or shore trips where you want simple, flexible aeration.

• Rechargeable floating aerators: Some list IPX7 water resistance and internal batteries (e.g., 2,000mAh) for cordless use.
• 12V portable aeration kits: Submersible pump kits with adjustable spray heads for customizable flow.
• Emergency hand pumps: Manual units with hoses offer a no-power backup for basic water movement.
• Capacity: Check GPH ratings on electric options to match your bucket or small tank.

Review each product’s power type, runtime, and included fittings to choose the setup that fits your fishing style.

Yes—this page includes replacement components that can help extend a pump’s life or restore function without a full swap.

• Cartridge motors: Replacement cartridges are offered for select bilge/livewell pumps and may note quick or click-in installation for compatible models.
• Automatic float switches: Options are available to enable auto activation with compatible submersible bilge pumps.
• Aeration fittings: Some kits include adjustable spray heads and hardware for livewell tuning.
• Match specs: Verify GPH, voltage (12V or 24V), and outlet size to align with your existing system.

Check each product page for compatibility details and dimensions before ordering, as components are typically designed for specific pump families.
