OMC shift converter box?

[drrm123]

Does anyone have any info on adjusting OMC shift coverter box for a 1981 3.8? i have seloc manual but not much info. the problem is when shifting into drive or reverse the interrupt switch does not move enough to depress switch. i tried lubing the bushing it pivots on but still wont work. it pivots back and forth when done by hand but not while shifting, it move about 1/2 the distance it needs to. almost like spring is too strong.

How are the cables, old? Can you adjust the end of the cable ?

Re: OMC shift converter box?

When you say the "interupt switch" do you mean the neutral lock button underneath the handle? If so, something has probably broke and you will need to disassemble it. There should be two screws on the outside of the top of the handle. Remove this and it looks like you can remove half of the handle. You should be able to see what's going on in there at that point.
I have an '89 OEM OMC manual open - not sure if they used the same stuff over the years though. They don't really have a good schematic of the controls, but many pix. Any chance you can post a pic?

p 10-49 thru p 10-53 you tried all that?

Re: OMC shift converter box?

In my manual the "Throttle and Shift Control Systems" is chapter 11. Again, mine is 1989.
It goes into great detail with a ton of pics and of course has a nice troubleshooting section even if it doesn't have a schematic or drawing of the remote controls.
Gotta love OEM manuals!
I'm concerned that drrm123 may have different controls.

He has the 83 i helped him before it's a stringer not covered bye the book you have, the shift converter is located in the back converts the throttle cable for the lower cable.

The book is 3400 in the right hand corner goes 1964-1986. For stringers.

Re: OMC shift converter box?

thanks for getting back so quick, the switch i talking about is on the converter box at the rear of the boat, i'll look on dougrussel site to see if i can find a picture and part # if not i post a picture when i go home today, the part pivots when shifter if pulled and pushed and its supposed to pivot to allow interrupt switch to pivot over and stall engine while going into gear. chief allen all cables are good and operate smoothly. also the picture on 10-49 if similar but not the exact same thing, my part has a second pivot point on the arm that should colapse when moved.

Re: OMC shift converter box?

My boat has the same converter i can't go look at it, but there are adjustments on the switch itself and the converter, you tried adjusting them, the holes are elongenated to allow for the adjustment.

Plus the screw on the actual end of the cable can be adjusted to make longer the travel of the cable, am i being clear?

Wish i could just come over and show ya just did that with someone else.

Re: OMC shift converter box?

Gotchya.
That was the other thing I had in mind - back on the starboard side of the carb (at least on my 4.3). There are a lot of things to adjust back there.
I'll wait to see if you can come up with a diagram or pic although I suspect we have the same setup...gotta run up and pick up a 'scrip - back shortly.
I can transpose the "shift system installation and adjustment procedure" if you like when I get back.
You haven't mentioned any shifting problems as far as going in and out of gear...is this correct? (concerned about cable adjustments)

Hope the ribs arin't hurting to bad. You got the x-ray nothin brokin i hope.

Young man take a break from it and go back to it with a fresh mind.

The adjustments are there it just takes time and patients, to get them correct.

Made me nuts also, and took a break from it, and came back the next day, and got it right, and so will you also.

Re: OMC shift converter box?

Oh i meant to post that the hastings adjustments are not for the stringer models, it's for cobra, useless for us.

Re: OMC shift converter box?

Thanks, went to a second doctor today and he confirmed - nothing on the xrays. The consensus is a sprained muscle - whichever one attaches to the ribs and goes on up to your shoulder blade. I still find this hard to believe, but it is better today and the CDS kept me outta work.

I see drrm123 hasn't checked back in yet.
I was going to recommend he do the cables first. They may never have had adjustments before (?). I would expect the lower to be gone by now.

Re: OMC shift converter box?

Mines still good, can say what you want about the stringers they used really,really good stuff.

Glad to hear about them maybe just being bruised.

Ahh legal pain killers. Better living thru chemistry.

Even make the lady look better huh ?

 

[drrm123]

Re: OMC shift converter box?

no shifting problems other that a little grind going into gear. will look at adjustment on switch tonight, have played with cable adjustment but ok, what you said about adjust switches that might work will let you know outcome tonight. at work now

Re: OMC shift converter box?

The rpms should be at idle in the water in gear 650-700 no higher.

Mines at 650, when you shift at a higher rpms it will make them grind.

And make the shift with authority, shift into gear not fast, just not slow, hard to explain.

A couple of brews on top of that and she looks even better...lol!

Re: OMC shift converter box?

Half way through this I thought probably had a stringer - too early for a Cobra.
Mines a Cobra. That probably explains the difference in chapters!
You're gonna have take the torch Chief...I'm no good with stringers.

On mine, when my lower cable started (actually finished) rotting through, it started grinding just because because of the extra 6" of slop. Go figure. They've got the cable run up through a tube full of seawater.

Re: OMC shift converter box?

A few brews on top of that some peoples 80 year old mother looks good.

Yea a stringer he got, helped him before, good guy just having a little hard time with his ole girl, he will get it sooner, or latter.

Re: OMC shift converter box?

I added a picture. I think it may be the way i'm shifting it, I always eaze it into gear, so that may be my problem. I think i'll try shifting it harder next time out before i do anything else. also have idle set at 550. Thanks for the help again.

Re: OMC shift converter box?

You got it to idle at 550 ?

Maybe the tach is no good, can you borrow a shop tach and verify ?
