Upper crank seal.

1990 90hp merc 2 stroke. Fuel leaking from below flywheel. I haven't got to disassemble yet to see exact location. Does anyone know if any helpful materials on this job. I know the flywheel etc has to come off using a puller. Thank in advance .

I was planning on replacing all hoses why I was in there? Is there anything specific I should check for?

I doubt it is the top seal leaking.

Best I can tell the fuel is pouring from there. It's definitely not the oil lines. Hope to pull the flywheel for inspection this weekend.

I have seen several of these seals pop out but most on V-6

Time will tell. I'm. A car guy not a outboard guy so Hopefully this isn't above my ability.

Tim is this the line that runs from the bottom of the case to the top under the fly wheel on the starboard side of the engine behind the oil reservoir??
