Re: force 90hp what year is it?serial#8858710
Yep, all 90 hp model serial numbers started with 0E and then 6 digits.
Example 0E138442
They started with 0E000001 in 1991
And ended at about 0E398000 in 1999
The only place you will find the model or serial number on that motor is on the id tag on the transom bracket.
If the tag is gone, you will need to id the motor by its components.
Start with the ignition, there were three types.
The easiest way to do this is to compare the parts to those in the photos and diagrams in a Clymer Force repair manual.
