Attwood 500 GPH Automatic Bilge Pump
The Attwood Sahara S500 Series 12V 500 GPH Automatic Bilge Pump is a popular choice for bilge water management in small to medium-sized boats, typically up to 20 feet and exceeding in some cases. Here's a breakdown of its features and considerations to help you decide if it's suitable for your boat:
Key Features:
Automatic Operation: Built-in float switch triggers automatic activation when water levels rise and shuts off the pump once the bilge is clear, providing peace of mind.
500 GPH Flow Rate: Efficiently removes bilge water from most small to medium-sized boats.
Compact Design: Fits easily in most bilge compartments, maximizing available space.
Submersible Design (in most models): Sealed for quieter operation and protection from water damage.
Easy Installation: Typically designed for simple installation with pre-wired leads for hassle-free connection (consult the manual for specific instructions).
Benefits:
Reliable Bilge Drainage: Automatic operation ensures the pump activates without human intervention, preventing potential sinking.
Efficient Water Removal: The 500 GPH flow rate effectively handles bilge water accumulation in most smaller vessels.
Quiet Operation (Submersible Models): Submersible design minimizes noise for a more peaceful boating experience. Not all Attwood 500 GPH models are submersible, so be sure to check the specific model you're considering.
Easy to Install: Compact size and user-friendly design simplify installation for do-it-yourself enthusiasts.
Important Considerations:
Boat Size: While 500 GPH is a good general range for smaller boats, consult your boat's owner's manual for the recommended bilge pump capacity based on your specific vessel size. Larger boats might require a higher flow rate pump.
Bilge Compartment Size: Ensure the pump will fit comfortably within your bilge compartment's available space.
Electrical System: Verify your boat's electrical system can handle the pump's 12-volt power requirement and amperage draw (typically around 1.5 amps for this model).
Submersible vs. Non-Submersible: Attwood offers both submersible and non-submersible bilge pumps in the 500 GPH range. Submersible models are generally quieter but might require additional ventilation to prevent overheating. Non-submersible models are typically more affordable but can be noisier. Choose the type that best suits your needs and bilge compartment environment.
