Amazing!
Over 1.5 million cubic inches of displacement. A 90 foot inline.
Burns 1660 gallons of fuel per hour at maximum efficacy. Getting to that point probably burns 3 times the fuel, but quick figures says it is 38 times more efficient that my boat.
Maximum horsepower at a mere 102 rpm. Bet that adds to longevity and low maintenance. 102 rpm...wow.
Checkout the size of that ring gear. Which brings the question. How do they start that monster, electric starter?, compressed air? or steam maybe?
