Armed with “Purple Power,” scrub brushes, sponges, and warm water, I cleaned the engine compartment this morning. Twice. I am now a fan of Purple Power. I had no idea it would be that effective, or that fast. I don’t know what’s in it, but I used gloves, like the label recommended. Anything that cuts grime like that needs to handled with gloves.
After a lunch break, I loaded the angle grinder with a cut-off disk and outlined a window in the glass on the starboard in-board engine bed. After prizing off the slab of glass with a big screw driver, I exposed a black surface. Pretty much what I expected to see. However, when I attempted excavate, the black material scared, but resisted my assault. Very un-rot-like. I expected it to crumble out, like mulch. It did not. Not even close. I tapped it with my hammer – but it was solid. I scraped some of the black stuff off with a chisel, and noted that it came off and left clean streaks behind. So the next step is to really take a dig at it. With difficulty, I chiseled a chunk out of it. It was solid wood. Apparently, this part of the bed is wet but not rotted. I put a flap disk on my grinder and took off the black surface material and came up with this:
I haven’t explored the other bed yet, but the lag bolts on that side were solidly gripping into the bed.
I think what I’m going to do is leave the right side open for a while to dry, then glass it in again, as well as insert a new piece of wood in the aft portion where it was mulch.
