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.

  • Output Cyl 2 from CDI failing Yamaha 115

    I replaced the CDI unit due to this with a used CDI unit and now this one is intermittent on the number 2 cylinder. One trigger coil controls to cylinders so it is not that. I can hit the CDI and it will start working again. I found a water leak that was spraying water all under the cover at high speed and this is corrected. I don't know if this helped lead to the problem. My thought is that maybe the water spray on the coil damaged the output of the CDI. The leak was near the #2 coil. Is this a common failure for the 115 or do you think it was due to the leak?? I swapped the #2 coil with #3 to see if maybe the coil will damage #3 out of the CDI. So far no more failures.

    Re: Output Cyl 2 from CDI failing Yamaha 115

    At the risk of sounding like an expert (I'm not) here's some logical troubleshooting tips for the $#@!!&^!! Suzuki. (I just spent two grueling weeks tracking down a similar problem on my '95 DT115. - The CDI will usually either work-or not...there is typically not any mid ground. - If you "hit it" and it works, I'd suspect a loose ground (or other connection)somewhere (the center screw where the CDI Black lead connects... I added another ground wire and attached it under another bolt-head. That wasn't the problem on mine, but it may fix yours. - If you swapped the Spark Plug coils and the problem is fixed, I'd keep my eyes out for a used coil 'cause that one is probably going bad. (I assume that when you swapped them, you bent some wires that had been making intermittent contact [arcing] to a new position which fixed it (for now)). - The advice several folks gave me was "See if the problem follows the part". If the swapping of the spark coil made the problem go from one to the other, it is definitely the spark coil (or wiring connections?). - OBTW- You DID clean/replace the plugs first, didn't you? Spark plugs are one of the cheapest things to replace, and most likely item to be bad on any outboard engine.FWIW- I identified my problem within the first 15 minutes, but was sure "It couldn't be that" since that part was new... Two weeks later (after replacing plugs, rebuilding carbs, tracing all wiring, swapping CDIs (twice), removing and replacing the flywheel (twice)- it was that bad (new) part.It sounds like you are almost there...regards,Jim

      OOOPS!! I thought I saw Suzuki, but yours was a Yamaha. Most of the logic is the same, but your CDI may be slightly different (and less expensive than a Suz.)DUH!Jim
