Diagnose compression problem Johnson 150?

[pastorbud]

Is there a way to find out if low compression on one cylinder on a 1996 150 hp looper (J150EXECD) is a bad head gasket or some other problem?

They use o-rings.----No head gasket in the traditional sense.

Wow. So can I just take the head off and inspect?

Yep......
