However if this sticker isn't on there I'm not sure if the age will be anywhere else on the outboard.
Do you have a serial number on the rib? the last two numbers normally tell you the age and that could be an indication if it's the original engine.
The 'T' tells you it's a 1995 engine but, like every other second-hand (sorry, 'pre-owned') engine, it had only done 200 hours when I bought it, according to the seller!
Joking aside, it's in fabulous condition and being one of the three cylinder Yamahas, it's a bulletproof piece of engineering excellence. I hope.
