Do you think I could pull the arm off? Just the two bolts and its free?

Negative, getting that steering arm off is a job and a half. Basically you have to strip the majority of the engine down. Removing the powerhead is adviseable, but at the minumum you have to pull the lower unit. Remove the 4 bolts that hold the lower mounts to the lower pivot arm. Then pull the upper 2 bolts out and remove the engine from the clamp bracket assembly. Then you get the fun task of removing the large nut from the steering arm and getting that lower bracket off and then slide the whole steering shaft out from the clamp bracket. I would just clean it up, OSPHO it, then prime and paint it.

So is this really an 85 horse with a 115 cowling or 85 model?

It's eaither a late 80's to early 90's engine, or a factory remanufactured powerhead. Aroundd 87 or 88 OMC didn't stamp all of the powerhead welch plugs with the correct info for all of them, and reman powerheads came with a number like this as well.

Stink, I'm at a loss there. That don't appear original from what I'm used to seeing.
I hope FERM sees this and can enlighten us.
My best guess is the powerhead is not the original one and that is a part number.
The 85-140 horse take the same block, I'm guessing the "85" portion is just the 4 cylinder designation not 85 horse, the "R" is for remanufactured and the rest might be the serial number.

FERM, I was slow posting.
Are any of my thoughts possible?
