OK, well not real close up pics, so hard to judge. BUT, is it the lower cylinder that reads low? If so, your pics make it look like there is a gouge in the cylinder head on the lower cylinder. If my eyes are playing games with me and everything is OK, then have a closer look at the cylinder walls. Any aluminum scuffs or gouges? If not, maybe the rings are just stuck. I’m guessing this is a fresh water motor, so go ahead and "try" to remove the exhaust cover screws to have a better look at the rings/pistons through the exhaust ports. Don’t force the screws if they are stuck, you will probably break them off which is a mess not worth making.
You could probably sneak a peek at the lower piston through the exhaust ports without removing the exhaust cover by just peaking up inside the manifold while rotating the crank.
Let us know what you see, or if my suspicions are correct about the gouged head, post some real close up pics of the pistons/cylinder walls if nothing else is obvious.
