    Freeze plug states C0089440.
    not sure if the C is for Canada C0089440 im guessing 1989?

    the guy whom sold this to me had a sence of humor and painted over the 9 9. there is a large 9 with a small 9 to the rright with a small bar under the second 9 if that helps.

    Any help would be appreciated

It looks like you have a 1977 Evinrude. It appears to be a very clean low time engine for its age.


If you want to bump it up to 15HP, go to www.shop2.evinrude.com  and select the correct year and HP, then compare the part numbers of the powerhead, carb, and exhaust system that are different between it and the 15 HP of the same year. That will tell what you have to replace to achieve 15 HP out of your motor.
