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.

  • broke wires coming from under top of motor

    I have an 80's model 90 hp inline 6 Mercury and was trying to get boat running to sell and discovered some decaying wires that come from up top and lead to to a little box with three connections. I can crank the boat fine and it runs fine on the water hose . was wondering what these wires are for and are they for the trigger assembly (I think). Didn't want to carry to shop if this is something I can easily fix myself. Need some help.

    We need more info, like what color are the wires. Its not the trigger as it would run if the wires to it were broken. It may be the idle stabilizer in which case you can take it off and throw it away. But you need to verify that.

      They are the wires from the stator. They provide the charging for the battery.
      Replacing the stator isn't difficult but you will need the proper flywheel puller to remove the flywheel. Don't remove the bolts from the center hub, use the correct puller.
      You let the factory smoke out of it. All products have smoke installed in them from the factory. You can not purchase this smoke. The problem is, when you let the smoke out of it, the part is ruined and you have to get a new one. I wish I could find a place that sold the factory smoke.

      Never argue with an idiot. They drag you down to their level, then beat you with experience.

        thanks for the help i thought thats what they were after i looked at it some more today. I also have some other wire that are decaying too after i looked even closer. but these can just be replaced since they are just switch box wires.
