Need help find year and info on older Yamaha 25hp 4 Stroke

[DamianJP]

Hey guys

Friend of mine was given a older Yamaha 4 stroke 25hp. I wanna say late 80's early 90's if thats even possible. When did they start making 4 strokes?

I need help with exactly what year and any info. Wiring diagrams schematics , anything.

Motor was painted black and I can only find a number on the freeze plug. Where should I look for a model number or any other number to help aid in the search?

Take a look....












Thanks guys,
DamianJP
