just aquired a 1990 stratos with a 2002 175 FICHT motor. good deal motor not running compression issue.
Compression check 90-90-85-30-90-90
put oil in #4 cylinder walls and compression 120
I think this rules out a hole in the piston.
So I believe it is a Head gasket or a broken compression ring.
Before I pull the head are there any other things to look for ?

yes I got a very good deal that makes this work worthwhile.
