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 threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • mercruiser 5.7 mpi distributor help

    I have a 2003 mercruiser mpi with the 555 ecm.Somehow my distributor is broken where the cap screws down to the distributor the screw flange is broken off so i only have 1 screw holding my cap on.

    Here is my question since this distributor does nothing but supply power to my spark plugs in other words the only wires that are used are the coil plug and spark plug connections. There is some sort of module but that is unused.

    The mercruiser distributor is like $750
    A brand new distributor with cap and rotor is $50 off ebay but fits a 5.7 vortec truck not marine

    Is there any difference except price.

    I dont beleive there is i looked at the one on my 98 chevy truck and they look identical

    Question #2 is it normal while on the muffs when you rev the engine to hit a rev limiter around 3700 rpm and smartcraft gauge reads over rev limit. never did this on water winds right up to 5000 rpm at least last season it did.

          Why rev that high in neutral? Bad for the engine. Engine prolly knows it's in neutral and will not go above 3700. When in gear, it will go all the way. Regardless, winding an engine up to full throttle with no load is not good for it.
