Default Leaking drain plug flange and Alpha 1 Cathode questions

The silicone to hold the nut temporaily onto the wire connector worked well!
Hopefully I will be ready and able to lauch next week. I also did not
realize the 3M 5200 silicone (for my drain plug flange) had such a long cure
time (48 hours for tack free and 7 days for a full cure). Good thing I got
it done yesterday and was scheduling to launch next week!

I also wire brushed the large anode (or cathode as mentioned before) and
have reinstalled it. It will be interesting to see how it lasts!

Yes I do think I will be able to hold the nut from turning through the
drainplug opening, so hopefully the silicone will be sufficient to get the
nut in position and started. And I have managed to trace the wire
atleast into a mass of other wires, but it is green so I do believe is is
a ground wire for electrolysis. Anyone know of any good articles on
electolysis and boats?

All three of mine are bolts and I found that I could hold the nut with a
finger thru the drain plug opening.

Just getting the boat ready for launch in the next week or so and I am
trying to fix up a couple things yet to do and have a couple questions:
1) My drain plug flange has been leaking, so I got some 3M 5200 silicone
to reseal it. When removing the flange to clean up the surfaces I
found 2 screws were self tapping (as expected), but the 3rd is a bolt
which appears to also hold onto a wire (with a crimped-on loop
connector). The long bolt goes through the flange and transom and then
suspect the connector to be held on to the bolt with a nut. The boat
is an 1986 model 268 Searay Sundancer and there is next to no room to
get into / around the flange at the inside of the boat to have someone
to hold the nut, so I am going to try a bit of silicone to hold the nut
temporarily onto the wire connector so I can get it started on to the
bolt. Does this sound like a reasonable approach or does anyone have
any suggestions?

Also I am not certain what the wire is actually even for, as it again is
difficult to trace down in behind and under the engine, but suspect it
may be for electrolysis or something. Is this a fair assumption or
does anyone know for sure?

2) I removed the electrolysis cathode (I think it is fair to call) from
the bottom of the transom housing (two bolts) to make it easier to paint
the housing, and noticed some sort of build up or contamination or
something on the surface. Can or should I try sanding or cleaning up
the surface to improve the electrolysis or is this natural and not
really a problem? My anode (on the outdrive) is eroding as expected
and there appears to be a little erossion on the two (screw-on) knobs at
each side on the lower part of the housing, so I suspect everything is
functioning there ok. Should the two knobs and cathode be replaced
periodically? I boat in fresh water on the St. Lawrence.
