I have an mid 80's 150 hp Mariner elpto that isn't running as well as it used too so I'm working my way through it. I'm curious:
1) What is the "normal" compression range of this motor?
2) What would be considered the minimum compression before doing a ring job?
3) And if the compression on any motor is low, other than poor performance, is there any engine damage that can occur if it is run like that (until I can afford to have that major work done)?
Thanks in advance,
Bob
