.........toolbox on your boat?

I carry over and beyond the basic tools plus a box of various stainless
steel hardware (screws, nuts, bolts, washers, etc), a spool of electrical
wiring and connectors/crimper, a 12v soldering iron and wire, a prop wrench
and replacement prop, an emergency belt as well as various engine fluids.

Sometimes none of these items will save you (as witnessed by my overheating
incident this summer). However, it is nice to know some basic emergency
repairs can be made and I don't have to bring tools to the boat when I work
on it.

So what is in your boat toolbox?
