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.

  • Upper Water Tube grommet replacement

    I have a johnson 1981 15hp j15ecis that runs fine, I just have no water movement. water pump, impeller, tubes are clear, water intake is clear. One shop told me the next thing to check is the upper water tube grommets. Looking at this exaust housing diagram, it is part number " 0324045 GROMMET, Upper, water tube" It is number 39 on the diagram off evinrudes website. There is oil on the water tube, so I suspect these gromets have deteriated. What is the best way to approach replacing those? Does the whole power head have to come off to get those or can the lower exaust housing allow access? Anyone attempted this before? I realize this is a lot of work, but I just can't figure out why water will not flow.

    You would have to pull the power head to get at the connectionand you would have to have a new gasket and grommet. Have you pulled the stat plate and hooked a hose to the water tube (after removing leg) to see if you get flow? When the motor runs do you get water from the tell tale? Best of luck. Rick.

      Well i just looked at the motor again this morning and there is oil coming down the water tube and yoou can wiggle the tube a decent amount. I think those seaals are bad and need to be replaced. Im curious to know after getting stuff removed and the motor mounts open, is it just a few bolts and the top will come off the exaust housing. Well see how it goes.

        Well, got the powerhead off today and everything got a much needed cleaning. Sure enough, the main water tube grommet is cracked and needs replacement. Everything else looks ok. Anything other maintenance suggestions or checks while I have this thing apart? I willl have it apart for a few days waiting for parts to come in.
