That is the question of the day, (besides what did that guy do last night). It’s orange, and I mean BRIGHT orange.
So what is this stuff we’ve been scraping away? Turns out, it’s Phillybond Orange, a two component, epoxy paste, developed for sealing exposed edges on stern-tubes. Which is precisely what it’s doing, bonding the stuffing box to the stern-tube. And quite firmly sealed between them is the inner cutlass bearing. And by all appearances, that particular bearing is years past needing replacement, which brings us to why we’re trying to separate that brilliant orange bond.
Here’s the outer cutlass bearing and stern-tube. If you look real hard, you can almost see the engine from here. So what exactly is the stern tube constructed of? Yet another thing to ponder.
