Control Cable Question

[MacDaddy21]

My control cables are not functioning properly. I have adjusted the barrel retainers on both of them with no results. Is it possible that they could be stretched?

Re: Control Cable Question

Take them out of the housing and let them hang over the outboard so you can see them move from the remote control. If not I would suspect the remote control.

Re: Control Cable Question

What are the symptoms? Is it possible you have switched them? As you push the throttle from neutral to forward, the shift cable moves first, and then stops and then the throttle cable moves.

Re: Control Cable Question

Basically, when I run the motor, I push the throttle into forward, and it engages the prop almost instantly. but there is no increase in the rpms until the the throttle is almost all the way down.

Re: Control Cable Question

I'm having the exact same concern with my mercontrol.

Re: Control Cable Question

still havent fixed this problem. anyone have some insight?

Re: Control Cable Question

That is not unusual. With the motor off, advance the throttle all the way. Now see if the carb throttle plates (butterflies) are all the way open. If so, the cables are fine. If not, it sounds like some adjustment or repair is necessary.

Re: Control Cable Question

from the description the shifetr linkage is too tight, and the throttle linkage is too loose. when you put the shifter in fowards it pulls the cable forward in to gear this means your cable is too tight engaging too soon. lossen that barrel up a few turns after the shifter engages the throttle cable pulls the arm and this adjustment is too loose not fully traveling the entire distance to open the carb all the way. Tighten this barrel up so it pulls at an earleir time thus giving it more travel

Re: Control Cable Question

I'm going to include a little sketch of how my box is functioning. the big black arm is the shifter arm. the line coming out of the top of that arm is when the arm is in the TDC/Neutral Position. the 2nd line is the position of the shifter arm when the motor engages in forward gear. the 3rd line running through the bottom left corner of the rectangle is the position of the arm when the throttle plate first begins to open.

the key is on the upper right side, and the cables come out there on the lower right, under the key. this is basically what is going on. The throttle plate begins to open when the shifter arm is in the position of the 3rd line

Re: Control Cable Question

Max, The fix may not be as simple as that. Normally you set the throttle lever to neutral and adjust the barrel to fit the lower clamp. Now you add some length to the throttle cable adjustment to "preload" the throttle when the motor is in neutral. This gives a positive feel to Neutral and makes sure the throttle is pushed against the throttle idle stop.

Re: Control Cable Question

Correct me if I am wrong, but I do have a problem with my cables, right? The arm shouldnt have to go all the way down before engaging the throttle at all, correct?

If your shift into forward occurs at line 2, then the shift linkage likely is too tight or not properly "centered" between F, N and R; I think there should be more movement of the throttle arm before it shifts. If you were to draw a line for when it engages reverse, where would that be in your diagram?

Line 3, is that when the first throttle pickup hits, or the second?

Re: Control Cable Question

As i stated your shifter cable is engaging to soon and needs to be slackend up. on line 3 it is way too lose and needs to be tightened up apearently aot. Kicking into gear should be about the same distance from the line 1 as line 2 equally in reverse same distance say 10:00 to 2:00. The diagram to me indicates your shifter is engaging at 11:00 and more than likely in reverse at 3:00 if not your cable is NG. Sorry I went for a walk with my mom in law and found what appeared to be stolen items from the marina around the corner and had to notify the sherrifs office. sorry for the late response.The distance also will have the same result as in fowards as far as throttle in the reverse position as well

 

[MacDaddy21]

Re: Control Cable Question

okay, well i mean, line 2 is approximately where it engages. not exact.

ajgraz - it engages into reverse at about the same distance away from neutral. from what i can tell, line 3 is where the throttle place first begins to open, and it is only slightly open at this point, so i would guess that is the first pick up

Re: Control Cable Question

ok you say you have a relative distance being approximately the same in F and R from neutral. That should be ok now make sure the trottle is in neutral and make sure all slack is pulled out fron the cable to the engine disconnected now line the cable up like you where gonna attache it to the linkage and see where the barrel is at. It should line directly up with the barrel insert hole leaving just a tiny bit of slack say 1 turn to allow the carb to fully close. If this still dosen.t open the carburetor fully when fully engaging F then there is something wrong be it cable throttle etc.

 

[Chris1956]

Re: Control Cable Question

Line 2 should be in forward, carbs still closed. Line three should be full throttle.
it sounds like you have a problem in the control, as I cannot forsee how the throttle cable could be that out of synch with the throttle and the motor still run.

Re: Control Cable Question

Unless the cable is missing some of the outer winding (Part of the casing) somwhere

Re: Control Cable Question

Mac;

Go here and download the copy of Merc Controls Newest Manual and it should have the single lever type that you have:

Once you get it, let us know and I'll get you the parts lisiting for it.

Like i said, mine is doing the exact same thing but my throttle cable starts to move close to straight ahead for forward and straght back for reverse. I'll try messing with it today and post what i find if anything out of the ordinary.

Re: Control Cable Question

I lied about the straight ahead and back. Pics are of the positions where cable starts to move, it this normal? WOT is where #3 is.
