    That cleaned up nice Don.

    Seeing the “before” corrosion reminds me that 2 years ago the seal on the backside of our impeller housing (yanmar 3YM30) failed. While we repaired the seal, we failed to clean off all the salt water that misted out previously. After a couple of months terrible corrosion showed up on other parts of the engine. Sad Lesson learned.

    Thanks for the post
