The Willie

[scubert]

My buddy matt t. and I had a great dive on the Willie last night. Kind of choppy out on the lake but the vis was pretty good (40').
I have been working on a dive slate sized map of the willie, so far I've gotten the blueprints and digitized them, and have been able to X off a lot of the interior wood walls that have fallen or been taken out.
We were doing some work in the engine room and I've run across something that I cannot answer on my own yet.
The plans indicate that there is an access bay for the driveshaft at the lowest level of the engine bay. This shaft can be followed all the way back to where the shaft meets the prop. I could not see any such door or passage. Is this a smear or blip on the (much copied) plans, or is the door buried in silt? or did I just miss it?
any info on this would be appreciated.
I'm attaching a small copy of the plan, it gets distorted when I convert it to a jpeg.
We're hoping to get these onto slates in the next couple of months.
