    my 90s vintage Fiat 2.0lt 16v turbo engined coupe runs at 98-111C, fans kick in at 108C. Heavily pushed to 330bhp and keeps running even at Greek temps (well wont push it throughout July and August with 36+C....)

    Doesn't mean I'm happy with that, I'm much prefer if it run at 90-95 especially with high ambient temps.

    EGT and wideband lamda sensors are the only safe way of knowing what your engine is doing, but not seen them used much in marine environments.

    Old quote but petrol (gasoline) is for poofs, absolutely zero point comparing one engine with another. Running temperatures have increased higher top tank temperatures, by use of higher pressure rad caps.

    EGT absolutely, and common in marine enviornment. lambda sensors in engines which do not operate stoichiometric (Diesel cycle as opposed to Otto cycle) pointless! However suddenly we are discussing combustion temperatures at same time as coolant temperatures, simply nuts.
