My mercury villager drains the battery in 4 hours..
You should first disconnect the battery overnight to see if it stays charged. If not, it could be an internal short in the battery. If ok, then look for the drain. WIth engine running at 1500-2000 rpms, the voltage at the battery should read 14 volts if the chargning system is working.

Yes, it is very possible that a small internal short in the starter or alternator can cause this. Sometimes the starter wires can lightly touch and cause it to lose a charge. There are a number of things that can short and cause a battery to die over an extended period time. You should probably consult a specialist because it can be difficult to track down.

It may not have one.
If there is no fitting on the bottom or the back side of the tanks, you would need to remove the lower hose to drain it.
