Common problem is junk in pee hole. take a coat hanger or thin welding rod and make sure it is clear.

A lot of those Merc V6s had the telltale downsteam of the thermostats. You will not have a telltale, until the motor warms up and the 'stat opens.

You might test/inspect/replace the thermostats. In addition that motor likely has a poppit valve. You might inspect/test/replace it as well.
