    Cracked upper unit housing at spanner nut

    Oops. Long story short, dropped the UU coming out of the PC oven and bent the receiver where the spanner nut goes on. Back in the oven then tried to roll it out. Cracked off the whole bent part like it was a plastic bin. How bad is this? Any solutions to fixing it? Or am I doomed to spend $300...

    Anodizing Outdrives

    Has anyone ever done this/had it done? I see this being much more beneficial than powder coating. "Paint" is not on top of the aluminum, it's in the outermost layer of it. Also better for corrosion protection. Don't know if the outdrive parts are anodized before painting from the factory...
