500GPH 12v DC Submersible Bilge pump with 3/4 outlet, manually switched. Great for cheap camp showers, water transfer, rain capturing, bait tanks, livewells, or any diy project. These pumps fit in smaller spaces like sailboat bilges, kayaks, inflatables and tanks- they work just fine in fresh or saltwater. The low amp draw is perfect for smaller outboards with low output stators. It is not advised to install a pump that draws more amperage than your motor can produce. For example 80s outbpoards in the 60hp range provide a maximum of 9 amps - that includes all electronics and charging any batteries.
