all Mercruiser carb OEM stock black motors 1996 (serial # break for 1996 only will determine either a 140 or 160 degree t-stat ) and earlier models used a 140 degree T-stat.
All MPI motors use a 160 degree and some closed cooling MPI motors use 170 degree t-stat
When Mercruiser ( really GM) went to the 8 bolt intake manifold (vortec) for the carb motors is when the 160 degree t-stat was used

forgot to add in my post above all Carb motors went to 160 degree t-stat very late 1996 for model year 1997 to current. There is no more OEM stock carb motors from Mercruiser starting in 2012 just new carb repowers for 2011 and back motors. Volvo got rid of carb motors in 2009 or 2010 FYI.
