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.

  • 1969 Johnson 55 hp

    I have this outboard. Its 3 cyl., It ran fine 10 months ago. Now trying to start andno fire. Appears to have no spark, checkedall plugs. Not very problable they all failed at once. Next thought is points. Where are they located and how hard is it to change. Any help is truly appreciated

    I am not familiar with that model, but I have a 79 Johnson V6. No points, it has a 2 powerpacks and six coils(one for each plug). I would assume your engine has 1 powerpack and 3 coils. Check those first.

      there are points under the fly wheel but they are unlikely to be the problem.On the left rear side of the motor (looking from front)you'll see a box with wires coming out of it (CDI,POWER PACK) what the tech. name is i am not sure but this is probably the problem. You can do a low tech test on it without removing it.One of the wires that comes out of it goes up under the flywheel it is on the same side of the motor behind the throttle linkage.It has a connector which you can disconnect and with the key on touch the wire coming from the box to the bolt that the the wire coming from under the flywheel is attathced to(good ground)to if you can hear a buzzing (electrical type sound) the box is probably good. If the box appears to be good an ohm meter connected between the wire you tested and a good ground will test to see if the points are opening . with the meter attatched and the key off rotate the flywhhel slowly and the reading should turn off and on. I am by no means an expert but i have owned a couple of these motors so i have some experiance.good luck and let us know how you make out
