drain 4 livewell

[WillyC]

Seeing that the floor on most 20' seacrafts is right at the water level, the only way to effectively drain the in-deck live well (which is below the waterline) is to pump it out. Your thru-hull fitting you place in the hull sides or transom for the live well will have to be above the waterline and thus higher than the drain in your livewell.
