Can someone please tell me the max rpm idol for the 1991 Evinrude Intruder?
Thanks.
What is your idle RPM now?
It is at 1100 rpm now. As low as I can make it go is about 950 rpm. I tkink I may have a linkage problem do to what seems like play in the rod that goes up from the throttle cable!
Check the link between the two banks of carbs most times somone screws with it and one whole bank is standing open.
Can you please explain further what you mean and I can not find any other way to adjust ithe idol except for the cable that comes from the control box. What is the proper idol rpm?
There is a thin bar that runs between the two banks of carbs (port and starboard) there is a Phillips screw on both sides, one has a roller and the other does not, remove the air box, look inside the throats of the carbs, engine off.
If you see any gap in the opening inside the throats of the carbs the Phillips screw on the linkage (thin bar) on the side with no roller should be loosened this will let the throttle plates on that side close and your idle rpm should return to normal.
Just a question, you are checking the idle with the engine in the lake, right?
Ok, I follow the rod that goes across the top. The drivers side has a vertical roller on it that sits against a kidney shapped cam. The other side as far as I can tell just goes down into the carbs. If I can see what you mean, what should the idol be? Also, I am checking it with the water ears on in the driveway.
I think you are on top of the motor, where I am talking about is between the air box and the front of the motor, the idle should be around 750 in gear with a rpm of around 800-900 in neutral.
You are correct. I was talking about the top of the engine. I will remove the air box tomorrow when I have good light and check what you said to. I will post back and tell you what I find. Thanks very much for your time on this. gegolden
No problem, let us know what you find.
I pulled the air box off and moved the control box lever back and forth in forward and looked to see any thing that moved. The only gas related thing that moved was that linkage that I spoke about on the top front of the motor. There is 2 vertical rods one on each side that go down into the 3 carb block on each side of the motor. These rods are connected by one solid rod that has no adjustment of any kind on it. These vertical rods open and close the butterflys in the 6 carbs. On the driver side there is a plastic vertical roller that is made on to the linkage. It rides against a horizontal flat plastic kidney shapped cam. The cam has a grove on the outside edge of it and what appears to be some sort of stop for the vertical roller. Is this where idle is supposed to be in neutral? In reverse, the roller goes up on the outside of the cam and stops before it hits the big rod that goes up to the top of the motor. That rod connects to a arm that goes backwards and connects to a rod that goes down the side of the motor that connects to a arm that connects the cable that goes to the control box. That cable has the wheel on it that can be adujusted. Again, is that stop on the cam supposed to the the neutral idle?
When it is against this stop, the butterflys are not closed all the way. I can adjust it to 900 rpm only no less at that position. What do I do next? Please help.

Opposite side (carbs port side from behind the motor) of the roller there is a phillips head screw, loosen the screw and see if the throttle plates close.
I will look again and try to find that phillips screw. If I find it, I will say to myself
"if it was a snake, it would have bit me". I will post back again with the results. Thanks for all your time on this.

So does the "port side" change over to the opposite side when in front of the motor?
Inquiring minds want to know.

Sorry for the delay in posting back, I have been very busy. Ok, I found the phillips screw on the passenger side of the motor. I unscrewed it and the butterflys closed all the way. I started the motor with the water ears on it and the idel was at about 950 rpm. With it set like this, there is no way I can get the little roller to set flush up against the little stop on the outsdie part of the horizontal kidney shapped flat plastic part. I took eveything loose that could be done, unscrewed every screw on all the linkage and adjusted the wheel on the throttle cable. To kept it at that
position for idel, the little roller had to be up on top of the plastic cam toward the big vertical arm that goes up to the top of the motor. I think this is where it is supposed to be in reverse throttle! With it here, when I go to wot, it only goes about 3/4 throttle or maybe a little less. With the little roller setting against that stop on the cam, the motors idels at 2000rpm. My question now is how or what do I do to get the little roller to set in the that little stop and not loose my 950 idel? Help!!
