Anyway to Seafoam (not seafood) mercury 6 hp 4 stroke top end without running it

Is there any way in which something can happen to the crankshaft inside the crankcase that would make it no longer line up where it should when the Piston is at top dead center? I'm wondering if something inside has gone wrong. Also what does the crankshaft connect to that holds it in the proper position? Is it connected to the drive shaft

does this tell you anything...the book notes that these timing marks should line up and it appears to be off...guessing this would mess with the timing...how in the world would these have come out of timing...i am also getting leaking of seafoam
passed the valves and passed the rings

Did your timing belt jump?

The little dimple on the camshaft gear (big gear) should align with a corresponding dimple on the crankshaft gear small gear).
