i noticed a slight rotten egg smell in engine
compartment couple weeks ago when i opened up the cockpit
locker and had the engine
room opened up. figured it was just marina smell. opened up engine compartment and cockpit
locker again today to get some work
done and smell it again. dont smell it on deck
so im guessing its my batteries
my two start batteries
are behind the engine a foot or two and the water heater
behind them. im guessing my batteries might be going bad. they are west marine/ sealed lead acid start batteries. at least 5 years old.
as luck would have it i just filled my heat exchanger
with barnacle buster and want to start the engine to flush it out. am i taking a huge risk by even trying to use the batteries once or twice more to start the motor
or should i not and just pull them both and replace first?
the batteries are sealed type. i dont see any leaks
or bulging near the top of the batteries and they are not hot at all but its been three hours since the charger
has been on.
