Saab 2000 engines?
 

Do my eyes deceive me, or are the engines on a Saab 2000 angled slightly to the right of the centreline of the aircraft (to counteract prop torque or something maybe)?

It's not unknown for single-engined aircraft to have the engine thrust line (and/or fin) offset to counteract torque, but it's normally only by a couple of degrees or so, and very difficult to detect visually.

I'm not aware of any multi-engined aircraft that have this feature, though I stand to be corrected.

There's a good hi-res photo of the Saab 2000 from underneath on Wikipedia Commons, if that helps:

When SF340 airframes were converted to Erieye configuration one of the changes was to angle the engines slightly to starboard to counteract the effects of the dorsal canoe. I don't know if that trick was shared with the 2000, but it did have an FBW rudder so may have had the computer handling the effect of the longer fuselage and additional thrust.

The initial SF340 flight tests were with "straight" nacelles, which presented the usual characteristics of propwash swirl. I think three airframes were built this way, and (1983) one by one they were reworked with canted nacelles, angled about 2 or 3 degrees to the right.

I have no knowledge specific to the 2000 with its bigger engines, but this is the background.

No- that's the one that I was on last week that had 2 bounces before finally getting down somewhere in the very far north of the British Isles. Bounces must have twisted the engine mountings a wee bit. ;)
