Sandspur has a point: Nigel Calder points out in his book that relying for DC ground return through a big black cable attached to the engine can be problematic, since among other things that design requires a very good connection between a good cable and the engine block. Checking and shining up that connection should be routine job every spring. I've seen a lot of rusty ones. He suggests a more complicated way of getting a better ground, but I doubt many of our small boats use that type of ground return system.

If that connection and the ground cable itself are good, then I agree with Kelly: I'd think I'd be checking all the wiring, switches and connections in the starting circuit to ensure sufficient electricity supply during cranking.
