What is the WOT engine temp for a 1986 Mercruiser 140?
Can someone give me the link to the manual or the manual # to this motor?

Should be 150-160? max. Gets cooler with more water running through, though so it may be cooler than that if everything is flowing well.

Should have a 140 thermostat in it.Mine run's at 120-130.Depending on water temps it will vary slightly.
