That should be plenty. A Westerbeke 30b3 isn't a huge engine. I would think that even a 50% charge would be plenty, as long as there isn't something else wrong with the engine that makes it "hard starting". If worse come to worse you can always use that 4D bank get her started. Starting a little diesel with a deep-cycle bank won't hurt anything.

How much battery charge to start engine
Hi All,
I'm scheduled to launch on April 17, and when I made the drive to the boat this past weekend to test the batteries, the starting battery (Group 31 lead acid) showed 12.52 on the multimeter, which according to a chart I found online is 85% charged. The battery is only a year old, and was topped off before winter storage (indoor heated), and ALL the batteries were disconnected from everything. This is the only battery that has dropped significantly, albeit slowly, during the winter. The two 4D's are still showing more than 12.7 on the multimeter.
Is the Group 31 at 12.52 enough to start the engine (Westerbeke 30b3 diesel) in a couple weeks?
As always, thanks so much for any help!
