Corrosion problem?

[Plankton]

Any worries about corrosion of keel bolts or grounding wires connected to keel bolts in a wet bilge?

In time, yes. You need to try to keep your bilge as dry as possible. Find out where you're getting water and fix it. If its from "natural" sources such as condensation from the refrig/freezer, from the air conditioning or shower drain install a collection box with overboard discharge. For practical purposes once your bilge stays dry, any water that later accumulates will provide you an early sign that something else is leaking. Remember, a dry boat is a healthy boat. Good luck.
