I went down to the boat today to check the electrical system (75 degrees 
today in So Cal so batteries today and on the water tomorrow!). The water 
level of both batteries was fine. Though there was no obvious corrison, I 
cleaned all connections and terminals. With the batteries disconnected, they 
tested at 13.6 volts. With the charger on, they tested at 14.45 volts. With 
the charger off and the engine running at 2000 rpms, they tested at 14.3 
volts. I was able to start the engine numerous times using each battery. I 
had a load test run on them and they checked out okay. They did say they are 
showing their age and will probably need replacing in about 6 months.

It seems like it may have been something with a connection I suppose. Thanks 
to all for all of the input!
