Yamaha 25hp Autolube 1996 Longshaft

I am in need of a new gearbox for this engine which is a 25N. I have been told by my local outboard repair centre that only a 25N will fit this engine. However, I believe it may be compatible with a 20D. I'd be grateful if anyone could give me the answer....Either way I am after a second hand one, if any one has one i'd be very grateful to hear from them.

Not sure, Don't have any parts listing for those models. If they are European models we wouldn't have any information on them.
