Not P but Moby-Dick (30)

[Mike Jing]

>From Chapter 48:

Why in the name of gudgeons and ginger-cakes don’t ye pull?—pull and break
something! pull, and start your eyes out! Here!” whipping out the sharp
knife from his girdle; “every mother’s son of ye draw his knife, and pull
with the blade between his teeth. That’s it—that’s it. Now ye do something;
that looks like it, my steel-bits. Start her—start her, my silver-spoons!
Start her, marling-spikes!”

What does "Start her" mean here?
