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.

  • Water Dripping From Hole Behind V-P Impeller Housing

    Engine: Volvo Penta 5.0 GXiB Serial #4012069514

    After running engine on muffs during the winterization process, I noticed water dripping from a small hole immediately behind the impeller housing that is mounted on the front of the engine. The small hole is NOT in the housing itself, but in a mounting flange on the pulley to which the housing is fastened. This may be normal, but I've never noticed it before if it is. I haven't found any mention of this in the OEM manual for the engine. Any idea if this is something that needs attention?

    A picture would help. I am guessing it is probably a leaking seal in the pump.
    When will people learn that impellers require regular
    replacement and are not drive it till it pukes items?

    If it ain't fixable - don't break it!

      Might be the weep hole for the pump, it possibly means the pump is on it's last leg. Take off the housing and inspect, you will know then what you need to replace. Probably should not run it next spring without looking at it.

          Yep! It is a weep hole to tell you the pump is near failing.
          The last Volvo i worked on had the same drip.
          No rebuild kit for the one i had.The pump was not cheap either!

            weep hole, means seal is leaking. They sell the seal separately but most times the bearing is toast and pump needs replaced.

              Thanks for the replies. Saying "the pump" needs replacing, I am correct in assuming it is the water circulating pump that needs replacing and not the impeller?

              Sorry that I don't have any pictures, but the hole is not in position conducive to photography. I had to use a light and mirror to find the source of the drip.

                  An update: It appears that this is an issue with the raw water pump and not the water circulating pump.

                    Had the same issue with mine - replaced seal, impeller, o-ring etc. and it's been fine so far after about 25+ hours of use. The key is that you catch it before the bearing goes out. If it wiggles it's toast fo sho - good luck
