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.

  • 1995 20hp fast idle lever

    I bought a new lever and idle wire. The wire was missing and the groove in the lever was damaged and it would not move while turning the knob. The new lever is part number 12805 3. It seems to be the correct one. But the old one is part number 12805 4.The new one molds around the carb and the carb cover and the old one bends away from the carb and the fuel line is in the way and the wire does not pass it. The biggest issue is the the wire does not advance the timing because it is too long. The picture of the idle wire is with the knob turned fully to the right. The last picture is the old lever.

        You have the wrong lever.
        12805 4 LEVER-FAST IDLE (1 required per assembly) (20/25) SN# USA-0G437999/BEL-9926999 & Below

          Yes I just put the old one on and pulled it forward and it pulls tight. But it does rub on the fuel line though.My first time ordering merc parts and I still find it confusing. I did not see the part number until after I removed it. Do you think the other lever will work if I shorten the wire? I only found one 12805 4 online and it is 22 dollars US. So with shipping and exchange it will be 50 dollars Canadian. The lever and wire I bought cost 10 dollars US combined, but with shipping and exchange it cost me almost 30 dollars. And I had to wait almost 2 weeks to get them.

            Try a dealer it is not an NLA part.


            • #7
              I just looked at the Mercury marine website and it appears that it is NLA. Also Iboats does not have it as well as many other part sites are listing it as NLA.

                If the wire is not popping out of it just use it the way it is. Or use epoxy to repair the old one. I would cut the wire as a last resort because you may not get the movement you need.

                  Is the wire meant to pull the trigger forward or just snug up against it? The reason I ask is the timing link is holding the trigger and the wire can not pull it forward.

                    -That is for the fast idle when you start it it will pull the assembly forward.

                      Okay thanks and sorry for the stupid questions. Right now in the summer I just prime it and go, but Last year I fished until freeze up and I had problems until it warmed up. Someone has offered me more than what I paid for this motor and I think I might sell it. Where I am it is hard to find long shaft motors in the lower horse power range. A little off topic but do you know what the difference is with a Merc sea pro? I did notice it has side shift, which is more my style. I have been looking at a 30hp sea pro which I think is a 2012 model. Are these good motors? Again thanks you have been very helpful.

                        The 2012 merc sea pro is more resistant to salt water. It is also built by tohatsu and is an excellent motor.

                          Alright thanks again.

                            Well I think I know why I am having problems to get the fast idle functioning. As I mentioned in post 9 the trigger is being held fully forward by the timing link. The link is in no way attached to the throttle. I think I am missing something and the previous owner just locked the trigger forward. By looking at other similar motors I would assume the trigger should be connected in some way to the throttle linkage. Sorry about the sideways photos again, they are not that way on my phone but for some reason they are sideways after I put them on the computer.

                              That ignition system is unique because the stator is held in place permanently by that rod. The timing curve is built into the switch box I don't have the manual for that ignition system.
