Hey Kevmart
How old is the wiring supplying power to the pumps. Typically, bilge pumps are replaced every couple of years, and the wires arent changed, just cut back to shiny metal.Could be corrosion in the run--or your connections--causing increased resistance and blowing the fuse.
Of course I am assuming the wiring is proper--i.e positive ( Brown, brown and white) to positive (red) and negative ( black ground) to negative.
Also, make sure the discharge side from pump through to the through-hull fitting isnt clogged or kinked.

Any time you blow fuses when you turn something on you have a dead short, a trick to try is to increase fuse size some (no more than 5) if circuit blows as soon as turned on its's a dead short. As Kevin said check your wiring good around pumps first most are wrapped together leading to frayed/ cracked wires touching each other.
Same problem with my Live Well/Aerator Pump and tried your "trick" Bonediver...with 5 Amp blows the fuse in about 2 secs. With 7 Amp it lasted at least 5 secs b4 i turned it off. Still didn't hear anything working??? It was running dry if that might make a difference?
