Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Jabsco impeller failures

    I have a jabsco 9001 - 777 raw water pump. We had an impeller get destroyed this morning due to running with the inlet valve closed. The valve was closed because the pump was leaking when not running.

    Another boater had an impeller that look like it fit but there was no part number on it that I saw. I installed it and it worked​ for three hours although it would leak quite badly when running. The shaft doesn't feel like it has any visible play.

    Looks like a seals gone. I filled it full of water and water leaked out the shaft.

    Anyone have any suggestions
    for me? Thanks

    You need a new pump, if it's leaking that badly, the bearings will be destroyed shortly, probably already are. Don't mess around looking for a cheap fix. If it fails you will overheat, and cause more damage to the motor, and costing a ton more than a simple pump.
    If ya can't fix it with a hammer,ya got yourself an electrical problem.

      Bearings fell good currently. Do you think it unwise to try to motor to my home with a new impeller and fix there? It would be roughly 15 hours of motoring.

        That is a loaded question, It could make it fine, or fail in the most inconvenient place. Do you have seatow insurance? It's a wise thing to have regardless, If you need a tow, with the insurance it's cheap, without its really expensive.

          Most likely the pump is shot.

          Spend the $220 for a new pump
