Re: mercruiser 7.3l dtronic
The temperature of the air coming directly from the turbo can be in excess of 200 degrees celcius, nothing abnormal about that as air gets hotter as it is being compressed, and that's the sole purpose for the aftercooler being there in the first place, to cool down the air going into the engine.
I doubt there are any specifications about what it should or should not be in the service manual, but maybe someone else on here knows the answer to that one?
Lykke til!
