Sorry to ask this but The only # I could find on my 18 hp Merc is 50-90983a1 and below 12 06 91. I look on the ID page and under 18 hp I can't find any of these numbers. Any idea what year? I was told late 70's.
If it does not have an ID plate, then look here.<br />www.myfishingpictures.com<br />Look a member unicorn's nice Merc cowling pics and you will likely find yours there. <br />Most are there from 74-86
