How could a "professional" fair over the raw water intake though-hull? I've yet to see one without a strainer grate. If the grate was in place, and you drilled from the bilge side with a 3/8" bit while in the water, then I would suggest you dive down to inspect the condition of the grate. Additionally, your engine will require a larger intake opening than 3/8".
I see a lot of problems with a "professional" fairing over a through hull in general.
But there are a lot of other questions I'd be asking too. Like, if the boat was surveyed, how the surveyor could possibly miss a faired over through-hull. Like, who did the work which resulted in the through hull being faired over. Like, did the PO actually inspect the most recent work done on the boat before selling it.
However, there are a few, albeit rare, fresh water cooled engines that do not require any sea water supply. They are setup much like the cooling system on a modern automobile, which also does not require a sea water supply to function.
I still don't see how any engine, gasoline or diesel, could run for over 15 minutes with out overheating if it requires sea water, and the sea water intake was effectively shut. A hybrid system (fresh water cooling, with a seawater heat exchanger) might be able to do it, but it should have shown some signs of overheating.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
