Just look at the connector at the battery. If it is corroded simply change the cables. It is an inexpensive and quick fix.
Just Make sure to use tinned wire, I used 1 gauge not 1/o with closed ends lugs . They are closed at the battery end and not subject to the fumes from the battery.

Eric, I had not thought about the condition of the cables as a source of my problem. I will cut back a cable and see what the condition is. My boat is a bit older than yours ,so that could be it. I need to resolve this before it gets me into a serious situation .The Scotchkote looks like good stuff.

Over the last 5 or so years I have encountered this intermittent problem.
With a new engine totally rewired by me and all new panel and wiring I assumed the problem was solved.
However, it was not. I found that Amel used welding wire and not tinned wire from the starting battery and the main switches. Additionally , the lugs that they used were open at the terminal end. Thus, allowing the battery acid laden air to enter the wire, When I cut the wire open, I found that it was corroded for almost 2 feet from the battery.-which causes a lot of resistance . The voltage at the starter motor was + or – 11 volts.
The Valeo solenoid is rather sensitive to low voltage.
Upon further inspection of the cabled from the starting battery to the vapor barrier connector was a completely different color than the wire outside the battery box.
I replaced the cables and used closed end connectors on the cables. I also soldered the cables to the connectors after crimping them. I then applied Scotchcote,
which is used on many underground connections.
Now the engine starts and stops like a charm. I also noted that the generator starts much more quickly.
While I was in the battery box, I noted that the common lugs posts for all the batteries were somewhat corroded. I loosened the nuts and applied corrosion x in between the lugs. My next project is to replace all the battery cables.
