Mercury 9.8 - 1981- NO WATER FLOW - HELP

I took my motor to the dealer and he told me the blockage is in the head/block. (Impeller and water up tube working great.) He said that the service would cost more than just buying another used motor. I have tons of time and lots of tools. Where should I start and have others solved this issue? Where is this "melted tube"/ "melted grommet" that I see on Google responses? HELP. Thanks for any guidance here.
 
Does the motor heat up? If no, the Tell Tale tube is blocked. (Shoot compressed air in with the motor running, or poke at it with a wire.)

If it still overheats, and the impeller is good, the seals on the copper water tube may be leaking (or the tube is not in the WP--seen that a few times).

Jeff,
The motor heats up real fast and real hot. Is the copper tube seal you are speaking of "inside the head"? Can I get to it?Thanks.

There's one at the top and bottom. Both have to be tight.

How' the impeller? If new, you can bucket test it. The photo shows how I do 'em and the amount of water flow to expect.
