Review on Amarine Made 12v Water Pressure Diaphragm Pump: High-flow, Versatile for Caravan/RV/Boat/Marine Applications by Nick Brunner

Works great so far, I'm a safari driver and this pump has been on my boat for about 4 months with no problems. Update: December 2017. We are sailing along the coast of Mexico with our sailboat. and the pump started to fail. Initially it worked consistently until our batteries were drained to a critical level. We only turned on the hammer when we needed a pump. Within a month it was completely out of order. I bought the pump in November 2015. It broke down in November 2017, it had a 2 year warranty and it broke down right after the warranty expired.
