How do you adjust the idle on this year model? I just need it to drop
a tad. Thanks, |

Disconnect the throttle cable from the motor linkage and verify idle is set
correctly (600 to 800 rpms in gear in the water moving forward). There is a set screw on the linkage that goes against a stop to adjust. Out of the water or in neutral it may idle as high as 1000 or more rpms depending on the boat and prop. The closer you can get it to 600 and it stay running smoothly and shift into gear without dieing the better you are for the gears. Once adjusted properly reconnect the throttle cable so it has not slop in it. Tony my boats and cars at http://t.thomas.home.mchsi.com wrote in message ups.com...

"There is a set screw on the linkage that goes against a stop to

There is an arm that goes to the fly wheel that when I move it back slows it down, but I was thinking that adjusted the timing and I did not want to set the idle by changing the timing. I did read somewhere that on that model, that was the only way. Any help would be great. |

If there is no stop screw then adjust using the throttle cable.
What you describe is the timing adjust. -- Tony my boats and cars at http://t.thomas.home.mchsi.com wrote in message oups.com...

On most old mercs the carb throttles are totally closed at idle (or should
be) and in fact it is the idle timing that is the final arbiter of idle speed. Just make sure you don;t screw wiith the max-avance timing or things could get ugly. Go over to iboats and search for a post I did entitled "timing and sync" - the search engine there is pretty good. -W wrote in message oups.com...

" The vertical arm on the side of the engine, the one connect=ADed to
the throttle cable itself, it has a lock nutted screw at it's lo=ADwest point, it's actually below the arms pivot point, down close to wher=ADe the throttle cable connects on. " Is this the one that is connected to the lower arm that is also connected to the upper timming adjustment arm? |

Yes.

Ok, I have backed off the screw enough where it just plays back and
forth before it hits the carb arm. even with it not hitting the carb arm (the arm that connects all three carbs) it still idles fast. Does this year model have an automatic choke? maybe that is what is stuck? any ideas? Thanks for eveyones help so far! |
