Does anyone know what the compression should be on this engine when new? Did compression check and all 6 cylinders are right at 110 psi (+or- 2 psi). Any help or comments would be great!<br /><br />Thanks...Doug

That's fine. As long as they all read about the same.

Yepblaze, thanks for the quick response! I was concerned because my Evinrude v4 120hp has over 120 psi per cylinder. Just wanted to make sure 110psi is normal for the merc v6.
