Buying Guide
Choosing the right auto bilge pump involves considering a few key factors:
- Pumping Capacity (GPH): Match the pump’s GPH (gallons per hour) rating to the size of your boat and the amount of water it typically takes on. A larger boat or one prone to leaks will need a higher GPH pump.
- Automatic vs. Manual: Auto bilge pumps have a float switch that automatically activates the pump when water reaches a certain level. Manual pumps require you to turn them on manually. For convenience and peace of mind, an automatic pump is usually the better choice.
- Voltage: Make sure the pump’s voltage matches your boat’s electrical system (usually 12V).
- Size and Mounting: Consider the available space in your bilge and choose a pump that fits comfortably. Check the mounting options to ensure easy installation.
- Durability: Look for pumps made from corrosion-resistant materials, especially if you boat in saltwater.
- Float Switch Reliability: The float switch is a critical component. Read reviews to see if users report any issues with the switch failing or sticking.
- Price: Balance your budget with the features and reliability you need. Don’t always go for the cheapest option, as it may not last.
FAQs
Q: How do I know what size bilge pump I need?
A: As a general rule, for boats under 20 feet, a 500-1000 GPH pump is usually sufficient. Boats between 20 and 25 feet may require a 1000-2000 GPH pump, and larger boats may need even higher capacity pumps. Consider the boat’s typical water intake when making your decision.
Q: How often should I replace my bilge pump?
A: Bilge pumps should be inspected regularly and replaced every 3-5 years, or sooner if you notice any signs of decreased performance or damage.
Q: Can I install a bilge pump myself?
A: Yes, most bilge pumps are relatively easy to install, especially if they come with clear instructions. However, if you’re not comfortable with electrical wiring, it’s best to have a professional install it.
Q: How do I test my auto bilge pump?
A: You can test your auto bilge pump by pouring water into the bilge until the float switch activates and the pump turns on. Make sure the pump is effectively removing the water.

Picking the right auto bilge pump is vital for keeping your boat safe and dry.
