I’m trying to order a replacement Thermostat but I’m getting conflicting part numbers at websites.
Our boat model year is 2003 and we have gas 5.0L V8 small block merc’s with MPI.
Some websites say I need 807252T2 others say 807252T5.
Does anyone know the difference between these two thermostats and what one is the correct one for my motor? I believe I need a 160 degree thermostat.
This past weekend we removed the thermostat in the port engine, heated until it opened, wiped out debris on the lip then reinstalled. It worked correctly a couple of times but then the slow long warm up time issue on just this engine returned. The next thing I plan to do is to replace the thermostat.
