Year model

[Bertil]

Hi, Can someone advise year model of my engine? It is a Yamaha 20 hp autolube, but as the fixing bracket has been replaced, the ID-plate is gone.
In the spare chart I do not find a 20 hp until 1996? but I have guessed it
is from 1989-1990. I have seen a picture in an ad identical to mine, where
it is said 1990. Mine has electrical start and tiller/remote.

I am seeking the CDI box ID.
Picture attached.

The only 20hp motors sold in the USA was in 1996 and 1997, if this a non-US motor then we would have any parts book on it.

non-US

It is likely not imported, so it must be sold by dealer here in Sweden.
