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.

      1985 Evinrude 115 Motor.

      We took it out to a lake near by and it ran fine for about 20 minutes, then it suddenly died. We tried to start it again and it tried to fire a couple of times but died. After getting a lift back to the dock it would start but only run for a few minutes. By the time we got back home it would run fine again.

      It was suggested by a boat dealer that I called on the phone that it might be the Power Pack, however, you never know how much knowlege people have, I thought I'd try and get some more info.

        Is there a way to test this yourself?

          I'm replacing my power pack tomorrow. We'll see if it was my problem. I had about 50 posts on here troubleshoot my ignition. If you search for 77Lark you might get an idea.

          I'll post my findings tomorrow.

            Bad powerpack -that is exactly what I would expect if the motor died like that because it would knock out two cylinders and shut you down under load.

            Then you get home and start it up with no load on the engine and wonder.

            I think you should ask the guy to explain what caused it to happen, and if the explanation is plausible, you better hire him.

            BTW, You may want to have someone check your rectifier to make sure that it is still charging. If you want to check it yourself, put a voltmeter on the battery with the engine off and take a reading. Then take a reading at the battery with the engine running and make sure that it is higher.

              We're hoping to be able to fix whatever it is ourselves, as everywhere around here is booked full, and it wouldn't cost so much then. Is that a possibility or does a professional need to do it.

                Its harder to diagnose than to fix, but it sure does sound like your problem. If you search 77larks thread like he said, i had a PP test in there you may want to try, follow his thread.

                      To 77Lark: The 80's 115HP motor has two powerpacks, one for each bank of cylinders.

                          It could have overheated and locked up.

                          The flywheel could be loose.

                          The fuel pump could be bad.

                          You could have water in your tank.

                          Your ignition coils could be bad.

                            Are you saying that bad gas could have caused it?

                              Gasoline floats on water. The fuel pickup line is at the bottom of the tank.
