When I bought the boat I found a 1" thru-hull that used to service
the POs generator
. The genset had been removed and the sea cock was closed. I installed a second A/C unit and used this thru-hull for the cooling water
pump. Three years later I installed a Northern Lights
6kw and thought to share the thru-hull with the air conditioner. It worked fine for a year and then the genset began to suck water
out of the A/C pump. Both strainers are below the waterline as well as the A/C pump and the genset raw water pump
. There seems to be plenty of water available to both devices when I remove either hose, but the genset wins the battle and the A/C gets no cooling
water. I considered installing some sort of reservoir or manifold before the strainers, but after thinking that through, I don't believe it would improve things. Is my only hope to haul the boat and install another thru-hull for the genset? I really don't want to do that. Any ideas?
