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.

  • Warning alarm before engine starts

    I am getting a warning alarm every time I start my 2003 chaparral 183 with a 4.3 mercruiser...all fluid levels are good...the alarm is constant and does not stop until the engine has turned over 2 or 3 times...it never sounds when running...to me, I would guess this is a bad sensor, right? The problem is that I'm not sure where this sensor is or which wires to pull out to test it...any help, thoughts, or pictures would be great thanks!

      Re: Warning alarm before engine starts

      There are 3 things that cause an alarm on your engine (assuming it's a carbed engine) High temp, low gear lube, and low oil pressure.
      When you first turn the key on, there is 0 oil pressure, which causes the alarm to sound. When you start cranking the engine, it starts building up oil pressure, and the alarm stops.
      It sound like your system is working normal.

          Yes, there is no timer on the oil pressure any more. There was for a few years, but they had a high failure rate.

          .it does this even when I go to restart it after its already been running...
          With the engine off, it only takes a second or so for the oil pressure to drop to zero.

              A Blown engine because you didn't notice the oil pressure was low is a lot more annoying.
