Why It Matters
Bilge Pumps Help Protect the Boat from Water Accumulation
A working bilge pump removes water from the lowest areas of the hull and helps protect the vessel from nuisance water, leaks, spray, rainwater, and onboard plumbing issues.
Marine bilge systems rely on the right combination of pump capacity, switches, hoses, wiring, check points, and regular testing to stay ready when water appears.
Match Pump Capacity
Compare GPH rating, bilge size, discharge height, hose run, and application. Higher capacity may be needed for larger boats or longer discharge runs.
Confirm Voltage and Wiring
Bilge pumps commonly use 12V or 24V power. Match the boat's electrical system and confirm fuse, breaker, wire size, and switch ratings.
Check Outlet and Hose Size
Verify pump outlet diameter, discharge hose size, thru-hull routing, anti-siphon needs, and space around the pump before replacing hardware.
Parts Desk Guidance
Pump, Switch, or Complete Setup?
If the pump motor has failed or capacity is too low, replace the pump. If the pump runs but does not start automatically, the float switch or control may be the issue. For upgrades, plan the pump, switch, wiring, hose, outlet, and access as one system.
Common Questions
Bilge Pump Buying Help
How do I choose the right bilge pump size?
Start with boat size, bilge volume, discharge hose length, vertical lift, outlet size, and the amount of water the pump may need to move. GPH ratings are measured under ideal conditions, so real-world output can be lower.
Should I buy an automatic bilge pump?
An automatic bilge pump or pump-and-switch setup is useful when you want the system to activate as water rises. Many boats also keep a manual backup or secondary pump.
What voltage bilge pump do I need?
Match the pump voltage to the boat's electrical system, commonly 12V or 24V. Also confirm fuse or breaker size, wiring condition, and switch rating.
When should a bilge pump or float switch be replaced?
Replace parts if the pump is noisy, weak, seized, corroded, intermittently running, not activating automatically, or failing a routine test.
