Help identify this Johnson OB pleas

So a buddy of mine comes up with this boat and motor and wants to try to have it ready by spring. I've managed to get it to start but now it's time to start ordering parts. The problem is there are no markings on the motor that either of us have been able to find. I've taken several pics from different angles, with and without the motor cover. We don't know what year model it is or what size it is. I'm hoping that someone can identify it from these pics. Thanks for any and all help. Let me know if better pics would help, I took these this afternoon with a phone camera. Here's link to the photo album.

After several hours of searching engine cover styles, I think I have it narrowed down to a 25R71S. [-o<

The tiller and controls on the front of the motor look like my 25 HP Evinrude.It's a 1984.

You can look it up online by Serial Number.

There should be a freeze plug on the motor with the numbers, look closely.

Here's the freeze plug, but I haven't been able to make heads or tails out of the number so far.

I don't know what that is, so no. LoL

I feel pretty comfortable after looking at all those motor covers that I have it identified. I wasn't able to find another year model or size motor that used those same badges on the cover. The raised letters name, and the plates on all four sides of the cover that all attach with nuts on the inside of the cover is a unique combination from what I saw.
