Nope not there. And if you look at the thermostat parts pages none of this type 40 has one. Weird. Temp is important to engine performance but not having a thermostat makes for a simpler design with one less point of failure.
Mercury Mariner 40 4cyl 2 cycle serial # 0D060736.
None of the thermostat parts lists show my outboard or any other 40hp Mercury outboard.
Do any 40hp Mercury outboards have a thermostat?
Thanks!
