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.

  • Fried electric board

    Okay so this past weekend the cranking battery died on my 2015 nitro. We tested the battery and it said it was bad. So we got a new battery no big deal. Well the next trip to the lake the on the new battery within 4 hours the battery died again so obviously there is something draining the battery substantially. Well that's the start of the problem. When trying to jump from the trolling batteries without me noticing my fishing partner hooked up the cables to each battery instead of just one (24 volt trolling motor). So the engine started and immediately went into guardian mode and would not let it run over 1500 rpm. Took it to the mechanic yesterday. They said it fried a board when we cranked from 24v instead of 12v. And they still don't know what is draining the cranking battery in the first place. So my question is does anyone know what board this could be that is fried and the cost. Also any ideas of what could be draining my cranking battery so much?

    Welcome aboard.

    What does the circuit board cost and what circuit board is it?
    1. What Merc motor is it? Never heard of a Nitro motor.
    2. Ask your Mechanic - He knows if he said it's bad.
    3. Why is the battery draining? See #1.
    Please, no PM's (Private Messages) regarding boat/engine problems.
