Seawater cooled water flow question

I have a 2004 Searay 240 Sundeck with a 5.7 vortec Mpi.

Background: Bought this boat with a cracked cylinder head. Motor was completely disassembled. All I got was three boxes of parts. The engine that was in it was a 5.0 Mpi. Serial# 0M620208. I decided to upgrade to a 5.7l since I was doing a complete rebuild on the motor. So everything is done, back together and ready to bench start.

Question#1: There are two hoses (1/4”) that are connected to the Seawater cooling system in the front of the engine underneath the harmonic pulley. I can not determine where they go. According to the service manual one runs back from around the fuel cooler and the other from the right side if the engine (seawater pump side)

I have posted a couple pictures to illustrate the hoses I am referring to. The first picture shows the ends of the hoses. The second pictures shows the diagram I am following and the yellow lines highlight the intended location.

Thanks for all your help.

Any

They go to the block drain positions. They are quick connectors.

They go to the block drain quick connect fittings

Perfect! Thanks both of you. I definitely did not have those parts in any of those three boxes. Thanks for the pictures as well. Worth a thousand words.

And if your smart you wont install that "quick-crack system" and the water dist ball is hollow inside too. The idea was good but the actual application is faulty . Once those fittings plug with rust and sand the block does not drain so the water thats left freezes.
