I just got this boat for dirt cheap, excellent condition except for 1 thing, blown head gasket.

Im having a heck of a time finding a replacement headgasket or new heads for this 71 mercruiser140 4cyl inboard.

Any help or tips would be appreciated.

Head gasket should be easy to find. Its still a current engine. Maybe you are having a hard time finding a gasket because you are looking for an iron duke gasket that was never used in a boat?
