Get a bigger hammer
OK so now for the serious reply, get a decent hammer and a large pin punch. Place punch on head of bolt and smack the punch hard. Then try to undo it.

If it does, then new gasket, re-assemble. Find where the screw came from, and locktite it back in ( if it’s serviceable). Have a great summer boating,
If it doesn’t, the head will have to go to a machine shop to have the seat and valve re-done.
There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats

Is there a butterfly valve in the inlet manifold? They are generally held in place with a smallish machine screw holding them to the pivot shaft. If there is and the screw has done what it has done and is missing the next thing to travel towards the valve could be the butterfly plate.
