I am guessing this is for a underground drill??? What else would need that much power?

Boats are ruled out because this thing weighs over 2000 tons :eek: Surely?

Just found out its for ships.

It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.

How does a single propeller put all that torque onto the tarmac, uh, water... ?

Surely with that much torque they'd need about 30 propellers, each, oh say 2 meters in diameter!?

Saw that before a while back, and it always amazes me. 5.6 million lb/ft of torque :D

They should make a VTEC version ;)
