Nothing like a noisy Detroit diesel. Having worked two summers on a power skiff towing the end of a seine net with a 3-53 running 1800 rpm with an open stack, I learned to live with tinnitus and the onset of hearing loss from a young age.
Driving home last night I passed an old GMC cracker box cab ramp truck with a tractor on the back. It was doing about 55 and had dual stacks. Sounded like it had a 8V-71 and it was by far the loudest vehicle I have heard in a long time. The driver was wearing over ear hearing protection and looked like he was having a great time and the two stroke sounded like it was spinning well over 2 grand which makes for quite an angry sounding racket if you haven’t heard one before.
Last summer went through 700 - 800 gallons so probably 2000 miles with a 6-71. Dry stack but had mufflers and I put a fair amount of work into quieting the thing, it wasn't half bad. And it always started right up.

All that running with no radiator ?
Ugh.
He is running fresh water through the engine with a hose the whole time.
They can idle for a fair amount of time with no water circulation without damage. They blow so much air through the motor that it's actually hard to get them up to temp at idle.I saw a rag stuffed in the outlet up top.
At low speed without a load they can go a long time without heating up, but under-load not so much, I had to use very large rads on the gen-sets I built with the 2 stroke monsters...Phil
Burn it up ? it's a 71 ! But since it's only a twin, probably couldn't throw more than one rod and have it keep running .... probablyWhy risk burning up an engine ?
