ok, my wife has asked me why our icebox doesn't drain. my guess is, the bottom of the icebox is below the water line. our icebox simply drains to a through hull fitting. i open the fitting while on a port tack and it drains. of course on starboard it fills. my plan is to plumb the drain to the sink foot pump and pump the ice box water to the sink. my wife usually has to take the time using a sponge to remove the 1/2 inch of water that remains after draining. any other suggestions? any one else with a similar icebox issue? thanks, steve and sue semenick
