Would this ballast work with a marine bulb?

You're better to buy a newer, higher efficiency ballast. You're not going to get much bang for your buck, or the light you want with a M57.

Checkout the charts and specs with different bulb and ballast combos. Interesting data for comparison.

But yes, in a nutshell M57 = Probe Start 175w MH, compatible bulb will work.
