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.

  • reed valves

    i have a 75 evinrude 70hp motor that was running great for about 4 hours then starting missing and running bad. we pulled the cover off and found gas blowing back out of the bottom carb. is this a reed valve problem and if so how bad of a job is it to fix this?

    Re: reed valves

    Yup, sounds like a reed problem to me. Get a manual. Then changing reeds is a snap. If a reed is gone or partly gone, be sure to check compression. If the engine has swallowed reed fragments it often gets a serious bellyache.Good luck and let us know what you find.

            Thanks WildeOne,guess I won't worry about it then.. I just figured if it happend frequently, then it might be a good idea to replace them with something that won't scour the bores or get stuck in a port when the piston hits it...regardsFrank

              It may not be that common for reeds to break, but they will quit sealing properly very easily. They get kind of warped, especially in motors that have sat without running for a long time.A bad crank seal can also cause this condition, as well as worn rings/cylinder.

                Hi ThmI would take it back to the shop - they must have forgot to lock or turque the little screw. I had a reed failure on my motor, i disassembled the whole motor just to discover the broken leaf was lying behind the intake cover at side of motor - suggest you try there if yours is broken
