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 else’s 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 it’s posted at the end of someone else’s 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.

  • Coil

    I have noticed while adjusting on my carb that the coil is very hot. The ignition has been converted to electronic ign. 1. Is the coil supposed to be hot? 2. Is the coil output voltage for points & electronic the same?
    This thing looks old... like maybe the original which by the way is a 1977 351W. Didn't know if I need a better coil for elec ign. I kinda of remember that engines back then a coil is a coil. The only difference was between manufacturers. Fords was several thousand volts higher than GM & Mopar.

    points run with 9 volts except for cranking which is 12 volts. the 9 volts is by either a resister wire or a ballast resistor

    some coils need the ballast resistor, some coils do not. if your coil is the original, it would require the ballast resistor. when you converted to electronic. did the instructions tell you to change the coil or run a ballast resistor. go back to the instructions

    coils get hot if the key is on and the motor is not running

    there are dozens of coil types out there, more than just output voltage. Ford, GM and Mopar as well as the rest of the automotive world all bought coils from the same companies. so you can believe all the hype you want. output voltage depends on windings and dwell time and will change a bit thruout the operating RPMs

      I did not convert it myself but I will take a look to see if it has a ballast resistor on it. Boat was running when I noticed the heat. This might be normal so I might be getting bent out of shape for nothing.

        Ayuh,.... Unless yer chasin' runability issues, I believe this is correct,...

        Everything on a motor runs from 'bout 140° to 180°, which is very Hot, to the touch,....

            all common electronic ignition modules are designed to work with a 1.5ohm coil, without a resistor... but a coil can get fairly warm when the key is on and the engine isnt running... if it gets so hot you cant hold your hand on it for a couple seconds, there is something wrong with the system and the coil is in in danger of exploding.... its not a big explosion or any electrical fires or anything like that, it just blows the top out of the coil and spreads hot smelly oil around and makes a mess, and leaves you without an ignition coil...
            a hot coil needs either a resistor added in the ignition wire before it connects to the + post of the coil.... or the proper coil installed.

                I am going to guess that you have a Petronics conversion. I just googled their site and if that is what you have it is compatiable with your current resistance wire. Of course they also say that for maximum results to add their coil. Check it out for your self. I have installed them several times with good results.

                  I have have seen many instances that Pertronix did not do well with resistance sources like wires and ballasts. ....and I do believe that Pertronix blaster coils want a full 12 volts.
