"the bulkhead has shifted due to the head lock." not familiar with that term, head lock.
The gasket, which always over time allows water into the deck coring - hence rotted core, was used because the top skin of fiberglass on the deck is too thin to support a rigid stanchion base.
If this was my boat I'd make sure that blower was working before trying to start the engine.
And I don't want to send you away BUT there is a Pearson owner forum here: Cruisers & Sailing Forums - Pearson Yachts The boat does have a blower to remove gasoline fumes, right?
Some of the fiberglass by the tiller is soft, around the stanchions has some cracks in the fiberglass, the "bumper" around the boat is broke and I'm guessing that is from the damage the dock had done to it during a hurricane.
One of the stanchions was over tightened and it's pulled through part of the fibergpass.
