MurrayM,
Sounds about right if the guy just "maintaining" the boat for awhile, though I probably would have just dropped in 1 of the cheapest 4D DD that I could find.
In any case, I suspect the whole electrically (DC anyway) needs to be looked at and evaluated; Start batteries and chargers, alternator(s) as well.
You will get Excellent advice here, starting with those Golf Cart batteries recommendation.
Best of luck to you.
