So i found a video by T-Mike showing this exact question . On a short shaft you need to remove power head to do the impeller. Those bolts release the power head from exhaust and lower unit in one piece. Mine is not a short shaft. Tomorrow!!!!!OFF WITH YOUR HEAD!!!!

One's been working on them since he was 14 years old, he's now 62 years old. He saw it in person, you all are giving advice on a picture.
Nothing is scored on piston or walls.
As far as compression goes, you know what it was brand new?
