    My 2858 Woes continue...

    I finally got around to removing my circulating water pump on my 7.4. The receipt I had stated it had been replaced in September of this year. The reason I was prompted to replace it was because the pulley was wobbling while it ran, it sounded like marbles rattling around, and it leaked water. Once removed, I found it was almost rusted through, the bearings were completely shot, and the feed/return hoses were completely corroded internally and dry rotted. I've since purchased all new parts and I'll reinstall this weekend. Have you guys ever done a chemical flush or something of the sort? I figure the whole engine needs to be flushed of the funk.

    Captain Obvious's first questions are: do you have a closed cooling aka fresh water cooling? If so, what are you using for coolant?
    That a water pump would go out that fast, if the work was actually performed, is odd, but it could have been the cheapest unit available. Yes you can do a flush just like a car or truck, just be very careful of any chemicals you use.

      “Almost rusted through”
      Sounds like she’s raw water cooled.
      Like Pete asked: open or closed cooled?

          Agree but even so to fail in 4 months! That's some salty water.

            Man, after following all the issues you've had with this boat, I'd be inclined to work towards "Tools Down, Lawyer Up".

              Could be the cooling system has been neglected weather it’s closed or open.
              I’d like to see detailed pics of the engine and drive on op’s boat.

                It’s raw water cooled and I didn’t do any work on this boat. This is how it was sold to me. I have receipts for this and that, that I’m starting to believe the receipts were falsified to help the sale.

                  I feel your pain... We dealt with similar issues in the past with an RV. I wish the timing would have worked out better...

                    Get a good marine water pump. You'll need to be careful to get either a v belt type or serpentine type because the operate in opposite directions. Then plan to do a flush with a product like salt away after every trip.
