I would replace it with ATC fuses and the fuse block for ATC. They give much better contact and don't tend to rot away as these glass fuses do in humidity.
I like these ones:

Not much to it in installation. Mark/label all your wires before you take them off and then attach them to the new fuse block. Use the same fuse rating as you had before and you are fine.
Be aware that some boats (and bayliners) have two different plus bars and the BlueSea ones have only one. That would mean that you need two of them unless they have one with independent circuits (didn't check).
Edit: they do have individual ones but only with 6 fuses....
