        The raw water pump on our boat showed evidence of leakage so I undertook to rebuild it. I’ve attached a photo of the pump ready to reinstall.

        I made a post on the sailboatowners.com website giving more details including a spreadsheet with Yanmar and Johnson Pump (the manufacturer) part numbers and prices from a few sources.

          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
