So...the 18 appears to be staying with me...going to keep progressing. (Honestly, for $350, I thought it'd find a good home before winter. Thinking I scared everyone off with the 'whole package' price...anyway...back to the project.)
The 2 bottom transom bolts have anodes on the ends. They look pristine, no corrosion at all. Both bolts however have quite a bit of corrosion on them...and its not rust, the metal has been eaten away. Enough that they've been weakened quite a bit, and are unusable.
I thought the whole point was that the anodes would protect the bolts?
