model and correct colour scheme

[swarrie]

Hi I recently bought a 40 hp pull start evinrude motor,hand controlled and I'm looking into repainting it to factory specs.as I'm unsure of the model and the correct colour scheme any input would be greatly appreciated. This is an old engine I would guess probably late 70's.how can I find out exact age for this engine please

OMC didn't offer any paint codes on the older engines. Post the model number and we can tell what year it is.
