I was only getting about 4" throttle movement in my two lever ratchett style shift box, so i disconnected cable at motor and it slides beautiffully, But why? My volume 1 - 1956 to 70 johnson evinrude outboaed tune up and repair manual 1.5 thru 40 hp by seloc publications does not cover this area. Is this re:tower shaft? shift lever slides fine

Re: no range in throttle cable

What you want to look at is the throttle linkage on the engine. Is the throttle plate(s) on the carb(s) coming wide open when the control is at far travel? What's the hp and year of your engine?

Re: no range in throttle cable

If this is your 1960, you won't get full throttle range unless you've got the engine shifted into forward first. If you look at the large, brass bar on the starboard side of the engine you'll see why.<br /><br />That brass quadrant bar is there to prevent you from overthrottling in neutral and to limit your speed in reverse.<br /><br />Sometimes (about 1/2 the time) you'll have to turn the prop a bit to fully engage forward gear when shifting with the engine stopped. Do not force the gear lever.

Re: no range in throttle cable

1960 #35520 40hp.The cover says evinrude Lark 40. So I'm assuming it is a lark 40. Is that a match with the engine #? It is converted to electric start with the rope part totally removed. I can not pull start it.<br />Past the brass shaft thing, where you slide the black hard plastic end onto a pin and put the little clip on to hold it. The piece I am trying to understand is referred to as "Lever" in a piece by piece drawing of a powerehead in my book. The bottom of this "lever" (that has the pin)comes out thru a small thick rubber bushing and near where i connect my fuel hose. the top has the thin rod connected to it up under the flywheel -- do you know the piece I am describing?

Re: no range in throttle cable

Hey girl!!<br />From what I understand, the part you are describing is the tower shaft. Don't know your 40 hp year but I have a '71 model E'rude that had the tower broke off when I acquired it. Right at the bushing. <br /><br />Haven't located one yet for replacement, but robbed the one off of my '59 Johnny. Same part and bushing. If I find one that I can use, I'll put the '59's back.<br /><br />Enough of that. Same problem. Wouldn't move enough and that was when I noticed it was "twisted" into by Bozo/Popeye/Hercules because it hadn't been greased (there is a grease nipple). Drier than a popcorn poot. Put that other part in and everything is lovely!!<br /><br />Check to see if it is way too sloppy right where the rubber grommet you mentioned is. Mine was hid from view until I took it apart. When it fell apart in two pieces I knew "what up"

I don't know how its supposed to move to begin with, but yes, its sloppy-- And i'm thinking it should have some rotation to it and there is not- in nuetral reverse or forward. Can you tell me what the thing right next to/connected to it with the wires is? So are you sayin I'm pretty much screwed as for replacing the tower shaft? is that fatal for my motor? I have a 1959 el dorado dorsett and I really want to make her work

Re: no range in throttle cable

Yes it should be rotation horizontally. There is an arm on the bottom of the tower that sticks out for the cable end to connect to that makes the tower rotate back and forth. The arm on the top of the tower is connected to the magneto setup that advances the timing and opens the carb via linkage. <br /><br />Mine was twisted into right under the widest part of the tower where it sits on top of the bushing (right at the cowling grommet). All it would do was wobble around. That's how I knew to disassemble it and look at what my problem was. <br /><br />No, not saying you will get prego from it, but you will need to hunt for a local "used parts man/gal" in your area as, if I remember correctly, one such source told me they were no longer available new. But there are bookoos around as they fit all sorts of models even with the part number being different. Just take it with you, if that is what is wrong, and match it up!!

Hang in there!! I'm slow to respond as I don't get on here often enuf, but when I run into things like this that I think, GODFREY DANIELS!! does this happen to everyone?!!, I like to know so I can see if it is a model/year/whatever related or just a fluke.

Re: no range in throttle cable

my neighbor was able to rotate the tower (more muscle) but said it too, is drier than a popcorn...... Grease it and work it he says.The slop at the bottom is about a 1/4" wriggle. Is that too much? How did yours get "twisted"<br />Grease? WD40 is as far as i've been. Brand - weight? I read that helps keep the water out.Any where else that should be applied?

Re: no range in throttle cable

Actually, you need to be putting white lithium grease in the grease fitting at the very bottom of the tower as it is a grease nipple but doesn't look like the usual. Should be a hole in the bottom of it and it will grease the bushing inside and out and the inside of the tower there where it rotates. <br /><br />Yeah, if it has 1/4" "wobble", I suggest that you look at it if the greasing does not help as it may be broken or at the verge of breaking. I really don't know what caused it as it was that way when given to me. I just assumed (and boy I hate that!) it was run dry.
