Standard super glue sets up instantly under very slight pressure. If you use it on a threaded joint it will set up before you the threads all the way in.
You might be overthinking it. Get a new coil and swap it in. Does not even have to be fully attached. A couple of zip ties will do. If that fixes things, swap it in properly.
You could remove the plug and measure the depth of the hole. Then you would know for sure.
I have two classic brass radiator petcocks on my 1976 120. I can never remember which way to turn them to open, then a wire won't go straight in, so it is hard to know if probing is doing anything. I...
Unless I have lost the plot, the compression testing was to indirectly confirm that the crankshaft and cam were timed properly, without disassembling the timing chain cover.
(1) "One turns but does not screw out" -- This tells me the interface between the tank and one of the female fittings is loose and unsealed. Prime opportunity for leakage and explosion.
(2) The main fill hose appears to be dated from 1997, long overdue for replacement.
(3) I think I would...
Unless you just really want to do it for entertainment, hard to justify the effort just to avoid doing the lead substitute thing, which does not sound like much of a burden if you're a typical weekend boater. For sure, driving halfway across the country for some parts that might not work seems...
The resistance wire sold as a repair part (84-94227A2) is a pinkish-purple insulated, thin, stiff wire about three feet long. Look for it as the last part of one of the wires going to the coil, though I suppose it could be anywhere.
In working on my boat of the same era as yours, I just assume...
Also, O'Reilly Auto Parts has Walker Products brand carb rebuild kits. Usually not in stock at your neighborhood store, but available within a day or with a shortish drive to a regional "mother ship" store.
I successfully rebuilt a 2Jet last summer with one.
OK, I have kind of lost the plot as to what your problem is. But I think I should ask what did you use to supply 12V to your coil after you removed the resistor wire?
Undo the resistor wire terminal from the coil. Don’t cut it. Coil or fold the resistor wire, which is now loose, back to a convenient location and zip tie it to something. You might want to reconnect it back some day. A few wraps of electrical tape over the bare terminal would be good.
I bought a '70's era Mercruiser 120 this year and just winterized it for the first time.
My understanding is that you can use automotive antifreeze. It just so happened that I did a drain and refill on three cars this year, and saved the old antifreeze. I have a lifetime's supply of boat...
