Those things can suck fuel, what does 100 octane cost today? $5 a gallon? so $2,500 an hour at WOT. Thats no wussy modern computer controlled engine, it is from a time when engines spewed leaded emissions, sucked fuel through carbs, and leaked oil like crazy.

Love PT boats, I have seen the ones in MA a couple of times. It must be really fun to ride one. 40 knots was amazing for a boat of that size in 1940.

$2,500 an hour......still cheaper to operate than many aircraft.

the front end of the motor reminds me of an old novi engine.
