Water Passage Question

[jerryny]

Can anyone explain to me the how the water passage section of the motor works. I am talking about the section at the top of the block where the lift bracket is attached. I can see that there a tiny hole at the top of each bank on the block. I am assuming that they go into the water passage section. Does it go anywhere from there? The water flow diagram for the Johnson 88 HP SPL doesn't show this section as part of the normal water flow. I am confused and trying to get a total understanding of my motor. Any information is greatly appreciated.
