Exhaust Gaskets

[Hopdaddie]

Had my oil sending unit go out on me. Pulled the log to get to the unit and noticed there is no manifold gasket. Can someone shed some light on this for me. I've never seen any type of exhaust w/o a gasket. The logs are Hardin Marine.
Thanks

Stick to the beer, leave gaskets to the knowledgeable.
