Perhaps it isn't "rocket surgery" after all, seems to me to be a valid question. At least it is fun to try and answer it. 
Capt F, you are correct, and re-iterate what I said, just shorter, slightly different and to the point.
I started my fifth NZ logbook recently, and interestingly at the bottom of the second page it says:
"Time spent in centre-line thrust aeroplanes shall not count as multi-engine time towards meeting a specific multi-engine time requirement." (CAA 1373 Rev 1: 09/2005)
I always understood that to be the case but then when I looked at my old logbooks I saw the same statement that flyby kiwi said. Hmmm.
This led me to the CARs, and under Part61 it is silent on the issue.
Wow. Maybe someone else can search the Rules. Far better than getting chopped 
@ the local, what fun!

Sorry to bring this thread up again, but things might have changed with Part 61.
"multi‑engine aeroplane means an aeroplane that has 2 or more engines, other than:
(a) a multi‑engine centre‑line thrust aeroplane; or
(b) an aeroplane that is prescribed by a legislative instrument under regulation 61.050 as an aeroplane that is included in the single‑engine aeroplane class."
So, with this, does that mean I must log 337 time as single-engine, or can I log it as multi-engine, but when it comes to flight reviews etc, a 337 cannot be used to maintain the Multi-Engine Class rating (or renew MECIR for instance).
Thinking logically (although it is Casa), flying a 337 isn't going to be much different from any other twin in normal ops, and in general practice, how often do you get an engine failure and asymmetric operations? I can understand that in flight reviews or other flight tests, that a 337 cannot be used, as in these times, asymmetric operations are to be tested on.

Oh good grief!!
our regulator does tie us up in knots doesn't it. I'm sure they do it just to have a laugh.
Them with proper regulations call it "Multi Engine Land".
I have around a hundred hours ferrying the sods of things...am I endorsed nope, aint gunna pay those ass..les for a piece of paper.

61.020 states multi engine centre line thrust aircraft are included in the single engine aeroplane class. You only need a design feature endorsement to fly this type of aircraft.
So a 337 is a single engine aeroplane with another engine added as a design feature!

Yes. In the event of failure of the engine, the secondary backup engine can be utilised to get you safely to the crash site.

Back in the olden days when I was looking for an airline job, most potential employers used to state in the application criteria "xxxx hours multi engine command time (excluding centreline thrust aeroplanes)".Pretty self explanatory, really: Pushme-Pullyou time was excluded by some employers.
Having said that - in Oz I would still have logged C337 time as multi (had I flown it), but simply deducted it from my total for an employer who excluded it.

Wonder what these guys logged. Two engines, centreline thrust, and shut one down when loitering - have to log multi for the multi part of flight, and single for the other? 
And they would have been under-qualified for any reasonable flying job they went for after their service?
