A previous owner labelled one switch position house and the other as start. We've only been using the house battery, even for starting. However, I'm finding that the start battery's voltage is down to 11.5v even though we havent used it. I'm thinking the bilge pump is pulling power from it. Is the bilge pump typically wired to battery 1 or 2 when the battery selector switch is off?
Which battery is my bilge pump connected to?

Does the bilge pump run when the start battery selector is off? Need to trace the wire from the bilge pump.
Check the terminals on the house and starter batteries to see where the light weight connections are.
If by some weird chance the connection to the bilge pump is further down the wiring, pull the (+) main wire off the posts one at a time to see who powers your bilge pump.

Actually, you have two issues:
1. To which battery is the bilge pump connected, and
2. why is one battery discharged.
as you have been told, trace the wiring. Nobody knows what a previous owner did to energize the pump or how he labeled the switch.
then trace how the two batteries are connected to the charger or via what interconnection, e.g., isolator, ACR, etc… they are interconnected.
