Chuck, While my 16,500BTU Flagship Marine A/C unit came with a CalMS580 pump. When I recently contacted FM about purchasing a spare, they recommended the March AC-3CP-MD-115V pump as a better replacement. They sell both on their website with the March pump costing $30 over the Cal. I have heard nothing but good recommendations for March pumps, so if I need a replacement, I will likely go with the March. See links to both pumps below.
