1989 to 2012 is 23 years, not quite 30(no more than 25 as that engine didn't come out until the first of 88). Yes they are old(88-91 vintage to be exact), but $1500 for a pair of them is pretty good. Come summer time the good one will fetch $3K simply because it is one of the most reliable outboards EVER built. They are gas hogs, but they can sure take a beating and go for thousands of hours. Sitting actaully does more damge to most outboards than useage. And they are known for sticking rings that take out a cylinder as I have Bradfords old engine here and that is exactly what happened to it.

Seems like my buudy has the same problem. Is there a common cause for this? Is it carbon or something else?

Will doing a Ring Free or Seafoam decarb help? If not can you fix just the one bad hole?

Being a large 2 stroke gas hog, they do carbon the rings up pretty bad. When they get carboned up they normally gouge teh cylinder walls and scratch which is where the compression loss comes in. Running the snot out of them, or decarboning them does the trick to prevent it from happening. Once they stick a ring, unfortunately you have to tear em down and have that hole bored and a new piston put in.

She ran like a scalded dog until I lost RPMs. I came off plane and she sounded like a spray paint can.

Spare told me they run the best right before they blow.

Ok then how about this............ a " deal " if the engine has full compression and putting out near 200 actual hp.
