How long would it take for a blue top optima to run down?

Will an extra 1.5 amp bilge pump drain a blue top optima battery during an 8 hour fishing day?

All of the electronics on the boat (except for trolling motor) is wired into this battery.

Any load on a battery will run it down. If that bilge pump runs for the full 8 hours it will "consume" 12AH of power from that battery. If it only runs once in a while I doubt you will have an issue. You will really need to find out what your other devices are "consuming".
