And not the paint kind of blues....although there's that too, of course!
For those of you not familiar, here's the setup of our engine/propeller... The "green part" is the Volvo engine that is being replaced for the emissions recall. The grey part to the left of the engine is the transmission. The green and grey parts are all "inside the boat". Below the black rubber seal is the "saildrive" and propeller. These are obviously in the water outside the boat hull.
We saw some corrosion on the edges of the saildrives when we had the boat out of the water last year, but we didn't have a lot of time to investigate. It seemed minor at the time and we replaced the sacrificial zincs that are supposed to corrode away before the precious saildrives. (We think the hard paint was hiding alot of the damage last year).
But now we've been scraping and sanding and it's obvious that the salt water has done a huge amount of damage, so they need to be replaced.
I didn't take a good "before" photo, but here's one of our saildrives just out of the water a couple of days ago. There is some corrosion, but we still thought we'd be able to treat it and repaint with special paint.
But that's not going to happen.....after we started really trying to get down to bare metal, it was obvious that the corrosion was just too much. (propeller removed).
So, we're getting new saildrives - this will likely delay us for several weeks if not more. Plenty of time to do all those other chores we're planning!
