Anyone know what the compression numbers are for a 3.0L merc 98?

Don't have my manual handy at work. It's at home. Does anyone know what the compression numbers are for that motor? Or have a link to the manual?

Ayuh,...

Somewhere between 150psi,+ 175psi is a nearly New motor,....

The manuals don't list a particular #,... Just that they are All about 10%, or less Different...

I had a compression test done today while getting my carb rebuilt.

they came back as
1=135
2=135
3=137
4=125

This okay? What issues if any should I be looking for?
