Re: Johnson / Evinrude 9.9 or 15 owners question

Vic. I had a better look at my motor this morning and you are right as rain. Thanks for that. Although my fix would work for his idle adjustment, moving that gear will move the cam further to the starboard which I believe his is too far that side already. I really thought I had the answer but I sure don't want to cause him other problems. I am perplexed as to what to say at this point. Maybe the wood block is the best fix for his situation. Rick.

Re: Johnson / Evinrude 9.9 or 15 owners question

ok I am bringing this back up...Its actually too far to the port side, so I do believe that moving the gear would work. My question is now, how does that gear come out again...I know the shaft that connects to the cam linkage just will come straight out the top, but what was the stuff about the lag bolt and stuff to get the actual gear out so I can rotate it 1 tooth?

Ill be honest, I dont know what a lag bolt is.

basically my question is that when I get the shaft out of the center of the gear, how can I get the gear to come out for the adjustment and then back in there?

I see the piece that holds it in on the parts diagram, but dont understand how it works.

thanks guys

Matt

Re: Johnson / Evinrude 9.9 or 15 owners question

Matt. See my post on the bottom of page one for details. If it doesn't make sense to you then let me know what is confusing. A 1/4 inch lag bolt is a hardware item you can get at any building supply for a few cents. It is used for bolting lumber together and is basically a large screw with a hex head. They come in all sorts of lengths and I would suggest 2 inches would be long enough. Make sure you ascertain the position of the two gears before you slip them apart to see if the alignment marks are positioned correctly or not. Best of luck and I'll be one happy man if this fixes your problem. Like I said before it has worked for me twice. Rick.

Re: Johnson / Evinrude 9.9 or 15 owners question

So does that piece have threads or is screwing it in just wedging it in enough to grip to pull it out? Reason I ask is because that article that guy wrote up about 9.9 and 15's says you can stick a screw driver in there as well.

I am going to attempt this without even touching the tiller arm and everything that leads up to the gear on it...will the 109 part come out with that other gear still in place?

thanks for all the help

Matt

Re: Johnson / Evinrude 9.9 or 15 owners question

Matt. The piece (107) is just round plastic tube with no threads. The lag bolt is threaded by hand inside of it just enough to grasp it and then you can pull on the lag and the part should come straight up and out of it's hole. I guess the right screw driver would work as well . The lag bolt worked really well. Gear 109 will slide away horizontally from the tiller gear once you remove the internal plastic tube (part 107). Let me know how it goes/works. I had a re-look at mine this morning and I see no reason why you would have to take the tiller gears apart first. I think I had taken mine apart to clean/lube everything. Rick.

maybe I missed something but there is a cam follower adjustment screw on models prior to 87. 24 in fig om6-1,cam follower is 11 in om6-1.These are on the carb.

Re: Johnson / Evinrude 9.9 or 15 owners question (update)

well as suspected by Vic, when I got the gears over 1 tooth (there is actually markings on them to get them in line)...well it shifts the rod over (part 108), therefore the linkage from the cam has to reach over there farther and that just still drags the cam too far to where the roller is still on the very edge not touching anything of the cam. Thats if the idle adjustment knob is all the way set to fast as it can go.

So, shifting the gears 1 tooth over, didnt change much, because there is a link that is attached to the cam under the magneto that has to reach over there and link up...when you pull it over to link up, it pulls the cam with it of course and pulls it too far.

I dont know what to do...I can just extend the idle adjustment part, but what can you glue to that part that will stick? it is very slick aluminum?

I guess I could always drill a hole in it and screw an extension?

I think there has to be a wrong part in there...either the piece that goes with the idle adjustment screw has to be longer, or the linkage piece from the cam needs to be longer. Either one of those would make it work.

another theory...look at my pictures and make sure my roller on my carb is correct...is it supposed to be thicker? Like maybe the outside ring came apart or something. If it were thicker, it might reach out and contact the cam when throttled down.

just a theory.

please post suggestions

I dont have the manual, could you reference possibly to the parts chart online?

Re: Johnson / Evinrude 9.9 or 15 owners question

Matt. I was hoping for better news. That Vic is no slouch. The link to the magneto. Is there another hole that is close by on the magneto plate? I'm just thinking that the arm could be connected to the wrong hole. As Vic has said there could be a wrong part in there somewhere but you should be able to measure the parts on your new 9.9 to confirm if everything is the same size etc., or maybe the parts are all together different due to the newer throttle. Steelespike is talking about the adjustment screw right on the cam roller itself. The one where when you turn it in the cam roller moves toward the cam. I know my cam rollers have small flat spots on them from wear but not enough wear to make a large difference. Well I just learned something. I was looking up the part number for the cam follower (#32 on the carb.) and your carb. doesn't have that adjuster screw. Both my 82-15HP and my 79-9.9HP have a different cam follower than yours. So that starts a new question for me. How does your manual tell you to set your timing? Do you simply loosen the cam itself and move it in or out? That is the way my 71-4hp works. With my 15 and 9.9 you adjust the screw on part # 32. I don't know what more to say Matt. I did cut a tiny hardwood wedge and glue it on the landing of the vertical shaft where the adjustment rod lands on my 15 and it worked well for a couple of years. I used Marine Goop and it never let go. Thanks for giving the gear adjustment a try. Rick.

Re: Johnson / Evinrude 9.9 or 15 owners question

I have now worked on about 5 of these motors and have had similar issues with the throttle not opening enough at low rpm (currently have an 86 and a 91). Looking at your pic - the second one - I think you can get a throttle roller (the white plastic bit on yours) that has a much thicker roller. In fact, compared to mine, I'd say something has fallen off yours - it looks too thin. If it had more girth it would reach. Take a look at another motor - many of these parts of kind of interchangable between models (but not exactly so) and someone might have swapped something over. Those white plastic things are real easy to break (but black on my motor). If you do get another one, go for one that has an adjustable screw on it (though they do tend to be a bit moredelicate - be careful).

the linkage that connects to the vertical shaft and then to the magneto is a fixed part...it isnt its own part, just part of the whole thing. It desnt have a part number, therefore I dont think I will be able to put that thing in a different spot.

Maybe the whole part has been switched out and its not compatible...I dont know. I guess for the time being, i will attach something to the idle adjustment.

my whole thing is not having an adjustable idle speed, but keeping the motor for dying. That can get annoying real fast when trying to go slow pulling to the dock or loading on the trailer.

I normally just find a good low idle for my motors and keep it there.

so, next thing...some motors are set up to where you can loosen something and then just manually adjust the cam? This one shows to be screwed in and screwed in a hole.

now thats the cam, the plate that the cam attaches to may have an adjustment somewhere.

I dont have a manual for the motor yet, and thats probably the main problem.

Don't know how to get to parts online but it is obvious.Port side of carb
cam follower has a roller on it. Follower has a screw in it to adjust follower so that roller is on timing mark on throttle cam just as carb opens as you advance throttle.Supposed to be on carbs prior to 87 and later models as well.
