Chrysler Motor Controls...(Hook Up HELP !!!)

[DarkeMaster]

Thanks to some folks here on the board, I was able to buy a set of controls for my Chrysler 55HP motor. I won them on eBay for about $48.00 and I am happy with that. The problem is; The controls seem complete and I understand the single shift lever (Clearly marked with a neutrel position)...But how the heck does the button work for the accelerator?????

The red arrow shows where I swapped the two armatures on the back because it was clear that the controls did not work at all in the position they were in. It was obvious to me (by the tool marks and inability of the shifter to smoothly shift) that someone had taken them off and put them back on the wrong way...

I am completely mystified about the Accelerator button and how it works. I am very mechanical but something seems amiss here...I attached a couple of pics (front/back) of the controls...Hopefully someone can explain the engineering on these things so I can grasp it...Or let me know if something is missing...For now I am stumped..

D Man...

OK, I have an older morse control, so we'll see what we can translate here..

When you 1st move the control handle, either forward or reverse, the gearing in the control will start to move the shift control cable 1st, quite quickly, and once the shift control is moved then the throttle control cable will start to move.

Hopefully based on that description you can figure out what cable is what.

For what its worth, you can actually use an OMC style 2 handle control on Chrysler's, provided you get the correct cable ends on the cables..

I'll check the operation of the control box I have that is like your and get some pictures..

I just got a 1975 Chrysler 60hp and have to admit I have no clue about the button on the control by the shifter. Ive pushed it and pulled it and dont understand its purpose. Hopefully I can gain some understanding of its purpose through this thread.

Trust me Nathan...., there are some fellas here who can enlighten us.

Sdunt, Anything you can do will be appreciated. I took another look at the control box and when I move the shift, there is no gear action happening anywhere inside. The shifter will shift the gears but nothing happens on the other cable AT ALL...I am perplexed to say the least. I thought this Chrysler 55 would use a dual handle control like the ones that evinrude uses. But I guess that would be too simple...

When I move the shifter from neutral, the shifter cable accuates and I know which cable is which, But the damn accelerator cable does nothing but sit there looking pretty. NO MOVEMENT AT ALL....I take it from your description though that there is some kind of gear that should push the throttle open the farther the shifter is moved? Is that correct? Because if it is, then I have a stripped out $48.00 piece of hooey on my hands...I would not be happy anymore with my eBay seller...

Does any one have a picture of the cable ends and their connection to the motor that will show me the proper connection to the motor. I know where they go, but am unsure of what stabilizes the cable to put force on the shift/Accelerator rods...

this is from a 1967 45 HP which may be similar to what you have for your 55

First of all, the control arms in the control box are in the incorrect position. The forward control arm in the box must be facing straight forward in neutral. The rearward one should be facing down as it is in the photo.

Forward arm is throttle cable and rearward arm is shift cable.

Now, when you push the control lever forward, The throttle cable moves, but not much because it is at the apex of the arc the arm describes. At the same time, the cable is moving the 1/4 to 3/8 spring loaded portion of the engine end quick connect back into the connector. Thus, until the lever is advanced about 1/3 of its travel, the throttle does not start to open.

There is a sector gear inside the control box which engages the throttle and shift arms together. While the throttle arm is moving forward (yet not opening the carb butterflies) for the first 1/3 travel of the control arm, the shift is engaging the gear selected. Thus: the engine goes into gear without the throttle advancing. After that initial 1/3 movement, the sector gear is no longer engaged and the shift stays in position no matter how far you advance the throttle.
The button on the side of the control box is pulled while in neutral to dis-engage the sector gears. Now, the throttle can be advanced--but only a little bit because of the neutral interlock at the bottom of the tower shaft. This keeps the engine from going into gear yet allows timing to advance a few degrees and throttle to open slightly for cold start, fast idle, warm up. After the engine is warmed up, you pull the control lever back to neutral and push in the button--re-engaging the sector gear and allowing the engine to be put into gear.

SIMPLE, NO?

Whoa! Eurolarva! I just noticed: You have the incorrect quick connect on your throttle cable. The correct one should be about twice the length and have a spring loaded center section. As I said up top, this should be pulled out about 1/4 to 3/8 inch when in neutral. The cables will work as they are, but will work MUCH better with the proper fitting. I think it costs abour 18 bucks.

Frank, I knew I could count on you. YOU ARE THE MAN. I get it. I knew that someone had been messing with the control arms. They just did not seem right to me. I knew there was a problem but could not see it through to find it...NOW... I get it....


Eurolarva, you too are the bomb...between the two of you ...By tomorrow.....I BE SHIFTIN BABY !!!!


Thanks Guys....

Hey Frank,

You still looking for some 55HP lower end parts? I may have some here real soon...From the cannibalized motor...I have to check compression on the powerhead..I may keep it, but the lower end may be up for grabs minus the prop...Let me know...

Thanks again guys...You are the greatest...

Re: Chrysler Motor Controls...(Hook Up HELP !!!)

I was studying that control box picture, and thought it should work if the arms were in the right spot, but not having hands on with it, or more, & better pics, I was stumped? Glad you jumped in with the solution Frank.

Hey Frank,

All I have is the cables, Where can I find these fittings (and what are they called). If you have a part # that would be great too...


Thank a million...

Re: Chrysler Motor Controls...(Hook Up HELP !!!)

give me your email and I'll send you the portion of the manual covering the remote control setup.

Re: Chrysler Motor Controls...(Hook Up HELP !!!)

Merc dealer should have the parts. They are the same for all Chrysler/Force.
part #24 Connector, throttle # A 587976-1, part #25 connector, shift #58685-2. This was out of a 1988 Force 125 factory manual.

Now, what I forgot to mention last night: The forward arm that connects to the throttle cable should have about a 1/2 inch kink upward to clear the shift arm and cable terminal when they both move. The shift arm should be a flat plate with 2 holes so you have your choice of which to put the connector in.

The lever arm is held to the control box with a set screw on the bottom. It is on a splined shaft so you can change positions but it is aluminum on an aluminum shaft so unless the control box is in very good condition, it may be difficult to remove (remove the set screw and pull straight out).

The reason I say this is because the sector gears have a neutral detent spring loaded ball. This detent should be when the lever is straight up. If the lever has been relocated, what you think is neutral may not be and you will position the arms incorrectly. So: be sure that straight up or close to it on the control lever is indeed neutral.

Re: Chrysler Motor Controls...(Hook Up HELP !!!)

Thanks Frank,

I think I have it now. I printed out your last email and played with it for a while today. Actually it is a really clever little mechanism. Someone at one time or another had taken this one apart because the levers were switched and on the wrong shafts. Guess they got confused when they tried to put it back together. I figured out the clearance issue on the curved arm..took a few tries but eventually my primate mind grasped the situation. I could not have done it without your help though..You're a pal...

Is there anywhere to order the connectors online. I don't have a dealer very near me? I will do some looking tonight and probably answer my own question. I am finally one step closer to taking her out for the first time. I'm sure there will be a few adjustments to be made here and there but it sure is gonna feel good to see it all work when I'm done....


I also put in my seats today, so the only thing left before her maiden voyage is a drain plug and a steering system (have one on order just aint got it yet). I am really getting anxious though to try her out...

After the first successful run then I'm going to be working on the cosmetics..Thst will really be s hoot....

Thsnks again, I really mean it...
