Starting in 1981 omc uses two letters in the model # to identify the model year. They used the word introduces to code the year. So starting with I being 1 or
I N T R O D U C E S
1 2 3 4 5 6 7 8 9 0
A model #e175 tlco using co would be 85
If you can't find the ser # tag look at the "frost" plugs it is also stamped there witch is also good if the powerhead isn't original.
I just thought this would be handy after this brp uses a year on the ser# tag
Wondering how to post images or maybe change your avatar or maybe something else?
