I've got a 1976 Chrysler six horsepower two-stroke. The forward cavity is not draining. Does anybody have a clue how to locate the drain channel? Do I run a drill bit down?
When the lower unit was separated it was full of water. Not the section where the oil is but above it. The oil looks great.

A piece of stiff wire or try compressed air?
I tried stiff wire, compressed air and lightly cleaning with a long drill bit. I see that the middle and back compartments are exposed to water but is the front one that has the rod that gets attached with a allen head screw to the upper case supposed to have water inside of it?
Waiting on my service manual to arrive, but in the mean time, when reassembling the sections, do I use a sealant?

No sealant at the surface at LU to midleg.
Yes, the cavity where the shift rod goes is exposed of water.
There is a seal for the shift rod where it goes into the gear case.
You might be seeing the seal from cavity or not. Do not have in my mind right now if the seal is push in from the gear case or from the cavity side.

Thanks for the info. For others that may need more in depth info, each compartment has a drain. The rear compartment where the shift rod is, has two drain holes.

We used a thin piece of stainless steel that was from a windshield wiper blade and a drill to get through all of the solid debris. It was very difficult as it was almost like hardened epoxy.

I could imagine in the winter that if it was not draining and water was sitting inside there, it might crack it. Well, mine is all better now.
Thanks again
