Reliable Bilge Pump - Works as Expected
The Attwood 4511-7 Sahara S1100 Automatic Bilge Pump has been a reliable addition to my boat. With a capacity of 1100 GPH and a 12-Volt, 1.5-Amp draw, it efficiently keeps my bilge dry and performs exactly as expected.Installation is straightforward, and the pump operates automatically, which is a huge convenience. It kicks in when needed and shuts off once the water is cleared, providing peace of mind while on the water.Although I’ve noticed the need to replace it yearly, it consistently performs well throughout its lifespan. For the price and reliability it offers, it's a routine maintenance step I’m willing to take.Overall, the Attwood Sahara S1100 is a dependable bilge pump that gets the job done. Highly recommended for its performance and ease of use!

Great quality bilge pump
Great quality pump. Exact replacement for my Sea Ray Sundancer shower drain tank. Fit was perfect! Pricey but my last one lasted ten years.
