2016 MerCruiser Engine manual 4.5L 250hp
Hello I have the newer MerCruiser 2016 4.5L 250 HP V6 motor built by Mercury Marine that I'm looking for the engine repair manual. I'm also attaching a picture of the engine serial number. In addition, if anyone can tell me where the thermostat is on this engine that would be appreciated. The engine's temperature has been running at about 125°, which I think is way too low so I'm thinking I need to replace the thermostat. The engine components layout is certainly much different than my last boat that had a mercruiser 2002 4.3L V6 GM.
