Just a comment on "two bilge pumps.... It is fairly common to install the
second (often larger ) bilge pump a few inches above the "primary and often
smaller " bilge pump. That way, if the first one doesn't handle all of the
water, the second one kicks in and can work in conjunction with the primary.
Of course, if both are connected to the same battery..and that battery is
down, it doesn't matter how many bilge pumps you have. If I had to leave my
boat in a slip, and it had electrical connections, I'd work out a 110 volt
converter to be sure that , if my battery went down, the shore power would
suffice. RichG

Thanks for responding Rich. Actually, I have access to electric only
after I come in from fishing, to re-charge trolling motor battery. So
I will have the cranking battery and the other too. How does this
effect the bilge power pump (s). I'm just not sure how all of this
electrical stuff comes together, in by bones I feel like I am going to
have a mess on my hands. Is there any way to use the cranking battery
for the trolling motor or bilge pump in case the other battery is ot
fully charged? I appreciate your help. Jack T.
