Help with Pumping Salt Water?

I'm trying to figure out how I can fill 55 gallon drums with sea water, without hand carrying 5 gallon buckets (very tiring) I need to know what type of pump I can use. I was thinking manual because I don't have a generator, but if I could find one that I could hook up to the battery on my truck that would do the trick. Any suggestions would be appreciated. Thank you................Tight lines
