If the bilge pump has to be replaced it is an easy do it yourself
project.

You should not need a charger if the bilge pump is the only thing left on
when leaving the boat. In any case do not run an extension cord to leave
a 110v charger running..........you are inviting electrolysis problems on
your boat and those surrounding yours.


Might want to re-think that advise.

1. Bilge pumps can run batteries down during periods of heavy rains and
the owner doesn't get to
the boat often.
2. Electrolysis is not so much of a problem in freshwater.
3. If you are correct, I better go down to the marina and tell the 300
boats or so to shut off their
battery chargers that are left running all summer (and winter, in some
cases).
4. Properly set up and protected, the potential for electrolysis can be
controlled.

Fair enough. I was repeating advice I was given by a friend of mine who is
an electrical engineer with NASA. David Pascoe also agrees.

And electrolysis is a concern even in freshwater.

Remember, we are not talking about permanently mounted chargers but portable
battery chargers run off extension cords.

YMMV.
