2005 Mercury Optimax 115 Compression?
There is a 05 Ranger that has a 115 Mercury Optimax with 320 hours that we are looking at picking up for our son. Compression test came back at right around 100 psi per cylinder. Is this adequate for this engine?

A little low for expectations- but that could be due to the test not being done correctly.
