A little surprising to hear talk of tightening battery cables at the battery
terminals with pliers?? Switch to clamp-on cable ends for high amp
connections such as starters. Those wing nut connectors are only useful for
connecting electronics directly to the batteries when there is no terminal
strip for the purpose. If you have a battery on-off switch those
connections should also be checked and cleaned and tightened if necessary.
As Dan suggested the CRC battery connection cleaner/protector is great stuff
if a little messy. It's red and never completely dries.

Invest the few cents for a battery cable end and clamp connector wire
brush.. A file? Golly, use the brush.

Obviously, if you're on the water and need to clean the connections and you
have no brush use something else.

Tim,

Tony beat me to it by a long shot. Maybe a different time zone??

I don't remember if I mentioned this in my post, but a file like the one
on a leatherman tool will do the trick on the lead battery posts in a
hurry. Don't forget to clean the corrosion off of the copper connections
from the engines. The file is also great for that.

Since you have one starting fine the corrosion is probably on the
connection to the battery from the other motor.

Tony, Dan,

Thanks - I'll take your advice and clean the heck out of the battery
connections (on both batteries), and recharge them. Hopefully that's
the problem. I tightened the terminal connection with a pair of
pliers, but they aren't too clean - that's for sure.

Glad I'm running twin 115's. This problem happened 50 miles from port.
