Secondary considerations for choosing the best spot include both freshwater supply and a convenient location for the seawater pump. When orienting the unit, turn it so the float switch runs fore-and-aft. Otherwise the machine may cycle erratically when the boat rolls on a rough day. Install a shutoff valve on the freshwater supply, too.
