My First 310 has an older 12,000 BTU Marine Air AC Unit (circa 1997). The seawater pump it uses is a 10 GPM March Pump. I have no idea whether this pump is the one installed when the AC unit was put in or if it is a later replacement. I am not impressed with the amount of water I see coming out of the side of the boat (relative to others I see on the dock). As yet, I have not attempted to try to see how much actual GPM it is producing.
Question One is: Is a 10 GPM pump a "proper" size pump for that sized AC unit?
Question Two is: What is the proper sized pump for a 16,000 BTU AC unit?
My installation only has about a maximum of a foot of "lift" from the through hull to the pump so the pumps should operate at max GPM.
What I am thinking is that if I need to replace the pump now, I might as well go with what would be a proper size for the next larger AC unit as that is probably what I would replace the aged 12,000 BTU unit with when it is time.
What say the knowledgeable Sailboat Owners out there.
