Ah yes rang the dealer and he said they put the numbers on a little 20c piece sized thing one the power head so that must be it and it is 1989 thank you
Ok thanks mate any ideas where they would be on the motor? Are they stamped in like a cars engine block? And no I'm not sure it's a 50hp, did they do 40hp 3cyl? On the Licencing papers it says 59hp but could of been changed since then
