Merc 150 and water flow

[tucson_boat_guy]

Hey all,
I have a merc 150. I have replaced all of the cooling hardware from the diaphram thing on the side to the thermostats and even a new water pressure guage. There still is very little water if any that comes out of the pee hole on the back of the engine.
I know this engine has a few mods to it but I have no idea what. Any ideas on the water flow. I have perfect water pressure that I check at the top of the block so I know there is plenty of water moving. I also watch the temp adn it is always at 150.
Any ideas.

Clean out the tube that feeds your pee hole. Also make sure the tube didn't come loose.
