OK, back to the "head gasket". I've never seen, on any engine, of any type,
(2 stroke, 4 stroke, lawnmower, motorcycle, OB motor, auto, etc, a "thin
rubber head gasket". I don't think any rubber gasket would take the
pressure and the heat. Could you be talking about the water jacket? Maybe
you could use a Permatex product called "High Tack". Paint it on lightly,
let it dry for 15-20 min. and it will hold. Should be available at any auto
parts store.

I am mortified. I have an Evinrude and the motor in question is my son's
and
it is a Mercury. I never saw it with the covers on and I always think
Evinrude.
A thousand apologies for my stupidity and a thousand thanks for your kind
responses. Bob
