Do you have a three position helm switch, On, Auto, Off by any chance?
Your fuse is good if it runs when the switch is turned to "On".
Hi GA, It could be that there are 2 fuses if the circuit is wired as Don suggests in this thread.

I agree that the bilge pump should have only one fuse, but circuits similar to Don's may have been adopted by others. It makes for confusing troubleshooting. - Grandad
