I thought it was the "golden" Hermatite that was formulated to never
go hard. At least that was the case when I was rebuilding British bike
engines in the 1970s. To my amazement, the stuff is still available,
and I bought some today....

Yeah, the temperature won't get terribly hot, since the joint is in
alloy which is connected directly to more alloy that is getting
dragged through cold sea water. Spares are rather hard to come by.
Hence my cutting a paper gasket. I ended up using Golden Hermatite,
and will keep my noodles crossed.. I figger that since Golden
Hermatite is still on the market after about 40 years, it must be OK.
In my day, there was Red Hermatite, Green Hermatite and Golden
Hematite. Red Hermatite was the sh*t we all avoided like the plague.
Golden Hermatite was useful. We never figgered out what Green
Hermatite was for. Or perhaps we did, but kept forgetting!

Thanks for confirming that. The old gasket certainly looked like
paper...

Yes, I purchased some "proper" gasket paper for the job.

I am sure it would. However, I have reservations about silicone,
because bits of it can end up causing blockages in oilways, etc.
That's why I ended up using Golden Hermatite. To my amazement, it is
still available nearly 40 years after the last time I used it.

Correct. Or, at least, 1/8 the way down the leg.  It's not gonna
get as hot as a head gasket, that's for sure.

I've read of gasketless exhausts in the comics where people have uses
silicone throughout, and apparently it lasts fairly well. >> Stay informed about: Home-made gasket for 2-stroke motor |

Nah - "figgered" is when you sit down with a cup of tea and a packet of
fig rolls to have a good long think about something.

Figgered is when you spend hours on the loo after eating a whole packet
of dried ones.

Thanks for the kind offer, but I am too far away, and I already have
some silicone gasket compound.

Thanks. That might even be the best option, since it would be less
likely to block up the 1/8" water channels that pass throught the
gasket... I ended up using gasket compound, and am now worried that
some of it might have squeezed out and blocked those water channels.
