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.

Stink, look on the left hand side of the motor on the top about 5" above the spark plug for one of these.
The first row of numbers is the model, year, etc. The next row is the serial #.
This is a 90 horse.

Oh, post that first row of numbers and letters. We should be able to tell most of the stuff about that motor, at least the year.

Also consider this thing if you ain't real sure about wanting to tackle the transom yet.

That was on the first site that popped up.
Different places have them at different prices, just gotta watch how much the "lower priced guys" want to charge for shipping.

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.
