I also live in the MD area (actually I live in MD proper) , and
"sometimes" isn't really a factor, and "cranking more than usual"
isn't either as long as it isn't the norm. I can start my engine at
freezing temps with maybe 5 revs rather than the normal 2. If your
engine requires alot of revs to start then a dedicated starting
battery is probably a good idea. But even so, 80A isn't a heavy load
for a decent deep cycle battery. I draw 50A to run the refrigeration
and 100A to run the microwave.

Yes, a deep cycle will start your Yanmar, but you are reducing the
life of the battery by doing so.

Not by enough that you would even notice it. A recreational boat
starts so seldom and a load of 80A isn't enough to do any harm.


Right, I agree. But, being in the MD area, I've got to consider
sometimes starting in cold weather and cranking more than usual.
