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.

  • 1970 Evinrude Kill Switch

    I have a 1970 Evinrude 25hp tiller outboard. The kill switch button was busted when I purchased it. Now the two contacts are just exposed and I kill the boter by touching both with metal and shorting it.

    How hard would it be to replace the button? Can somebody help me out with instructions/part numbers.

    Thanks, this site rocks.

      any momentary switch will work, just connect one wire to one side the other wire to the other side. put some tape on the wires and forget it, and use throttle to kill motor.

        I Personally don't run anything without a Lanyard kill switch. You can pick a Generic one up at any boat store. you may have to drill a hole for it, But It could save your life.

          I just move the throttle stop down and kill w/too low throttle. And no life jacket..

            Well, i found a kill switch for 30 bucks at a local boat repair shop. The nut that holds it on inside the housing is a REAL tight fit to get a wrench on there..... I am guessing impossible without removing items from the front of the motor.

            First I cut the wires from the back of the old switch. Then I wedged a scew driver on the nut to stop it from spinning and used a wrench on the old switch its self to spin it loose.

            I then held the nut still with with fingers and screwed the switch round and round into the nut inside the housing.

            I would suggest this method for those attempting this repair...... as turning the nut its self would require some wierd bendy wrench nobody owns.

            ** Time for install was about 20 minutes, saves 150 bucks in labor.
