List price is $63 but our distributors usualy sell them for cheaper.
Even if it siphoned out most of the water in the system....it would only get as far as the priming chamber...once the outlet side of the pump was suckign air it would just bubble up through the camber...and maybe empty out the inlet line....there "should" always be enough liquid in the chamber to draw fluid the next time you use the system...unless you go thrashing and empty more fluid out. :)

Oh boy!!....i think i just had the single most insteresting conversation with a boater ever! I just got a call about one of our pumps from a guy thats installing a Trane 3 ton HOME AC system on his boat!!!!!!! :eek:
From the sound of it he's gonna be spending more on retrofitting this into the boat then it would cost him to just buy a proper system!!!
