The model number plate does confirm the stern brackets were from a 1971 6 HP
Just guessing, but since it was made at the OMC Belgium plant, it is possible that it was a kerosene model that used a 10 HP block but produced about 6 HP. Those were common in Europe as gasoline is expensive and was used only for starting and warming up the motor, then switching over to kerosene.
If that was the case, perhaps someone replaced the block with a 10 HP gasoline version.
Most of the 1960 era 10 HP motors up to 1963 - the last one - had similar parts so you can obtain about anything you need for normal maintenance.

That these motors can take kerosene is intruiging. I dont know how much kerosene costs at the moment around here.
I will check all the evinrude motors for their cylinder heads and see which engines used mine.
by the way:
She had this fuel pump which wasnt working. Until when did they use these huge fuel pumps? I replaced it with one of the small newer ones. I wanted to open the old one but i cant do it. Do they normally fall apart when you remove the screws? Maybe somebody glued together the layers.
There's a paper gasket in there. It always tears takiking them apart. Should be a boss proud on the side of the pump. A flat blade screwdriver and a light twist and there ya have it
