You will need to find a power supply that can change 120V AC to 12V DC and can supply at least 5 amps of current. The problem you are facing is that this fan is made to operate off the electrical system of a boat, which is a 12V DC system with a battery and an alternator, similar to a car. The wall plugs in your house are 120V AC, a totally different animal. I did an internet search, and found some supplies that would do what you want to do, but they are pricey. I'm sorry to say that the price of the bilge blower plus the price of the power supply may exceed that of a 120V blower that you could just plug into the wall. I hope someone else can give you a better report.
