My raw water pump and livewell pump share a single thru-hull fitting. The livewell pump sits on top of the shutoff valve. I think it has a bypass to allow water to flow to the washdown pump. How does one go about winterizing these pumps? How do you get antifreeze to flow through each pump and the associated hoses? I assume this must be done when the boat is on land, but can't figure out how to do it.
