Default PT-109 water exhaust?

I will install a bilge pump in my 1/32 PT-109. It will take water, I'm sure, and a water detector will run the submersible, 5V pump.
Ideally, the water should exit through water exhausts from the engine cooling system. Did the boats have those exhausts, and where?

Thanks,
Robert

Since the Packard engines were water cooled, there has to be intakes and exhausts for the cooling water on the hull. I'm going to assume the intakes were on the bottom of the hull since anywhere else wouldn't be able to pick up water. As far as exhausts, I'm posting some pictures of some PT-103 class boats, out of the water and on the ship's deck before being taken to the Solomon Islands:

Just found a shot of PT-103, lead boat of the class, without it's mufflers and running at slow speed. Apparently, the water is dumped out below the engine exhaust so it's not visible when the mufflers are installed as it appears to go into the mufflers

A bilge pump is different than motor cooling. Is the OP trying to replicate water cooling, or removing bilge water? I doubt that the latter discharge would be through the motor cooling system.
