Yamaha control box problem

earthdog1970 · 30 May 2013, 20:44

After recently talking about this with one or two boys on this site, I was hoping I had this sorted, but unfortunately not, same old problem with my Yamaha 703 box and my Yamaha 40 hp 2 stroke outboard. The problem is that after putting on my new short cable ends on as advised I can still not get full movement between throttle and gears. If I take the throttle off at outboard end I can get full gear movement, but when I put the throttle back on I can not get either or, they just will not work out together. I know it has to be a cable length thing, but what? Please HELP as it's starting to get to me now... what am I doing that is not right?

Are the cables screwed well into the cable ends? If no slacked the nut off and screw them in a bit more.

Have you adjusted the cable ends at the outboard end? I used to run a Yamaha 40hp with Teleflex 33C cables and a Quicksilver remote. The threaded cable at the outboard end probably only went half way into the plastic connectors, then the locking nut was tightened. I thought the cable should have screwed in further. In addition, check the throttle and gear selection are well lubricated.

Has the impeller been changed recently? Only reason I ask is that the gear shift selector would have had to be released to drop the leg, possibly needs adjustment?

I have tried them right in and right out at both ends, but nothing that i do seem to make any difference, and i do not know about the gear adjustment but i know it goes in OK when just gear cable on or by hand .

I'm looking at that pic, and it looks like your control box might be assembled wrong if that's the position your cables are with the lever in neutral.

I thought so .. No reverse ?

Tim M · 30 May 2013, 21:36

I'm sure you have checked this, but, are you sure you've got the cables connected the right way round. Ie not throttle to gears and vv.

That's what I'm seeing too.

It's actually quite easy to put the 703 remote together wrong, and it all looks right til you try and use it.

Does the fast idle lever move when the control box lever is in the neutral 'locked' position?

Tim M · 30 May 2013, 21:39

Valid point Nos. Perhaps the handle has been reattached while the control box wasn't in neutral.

earthdog1970 · 30 May 2013, 21:40

Sorry it maybe that it was not in neutral between the two pics being taken, hence why it maybe looks wrong, but i have turned the handle around on the box to put it on the other side, not that this makes difference as it did not work on the other side either .

Tim M · 30 May 2013, 21:43

Is there any chance that when you swapped the handle around that it was maybe in the "full throttle" position when you took it off and you've accidentally put it back in the neutral position?

Bigmuz7 · 30 May 2013, 21:44

So it's a lhs box then ? Then the cables show forward gear full throttle yes ?

earthdog1970 · 30 May 2013, 21:47

I have made sure it was in neutral when i first connected up the cables, but no good, and then adjusted them up to as far as they will go both ways, still no good .

The box will always be in the same direction relative to the boat no matter which side it's mounted.

In the pic of the control box, it isn't in neutral, but the lever is. I'm not looking at the motor yet, it's the second step after making sure the controls work. Something's wrong.

Ok, best start from the beginning.

Disconnect the cables at both the box and at the motor so they aren't attached in any way to either the control box OR the motor.
First, put the handle on the correct side of the box (IIRC the neutral detent won't work if you swap sides)
Make sure the neutral detent works.
Make sure the fast idle lever will move when the neutral detent is engaged.

If you don't have both of them working, your positioning will be out and the controls won't work properly.

This should give you one cable mount in the dead centre,and the other should be all the way over one side.

Once it's like that and works, post a pic.

Yes - the handle needs removing and putting back on relative to the internals.

Yes, and IIRC, the neutral detent wont work if you put the handle on the wrong side.

earthdog1970 · 30 May 2013, 22:12

OK going to put it all back as it was before and try that, was only putting it on that side as seemed to work out better with outboard,and keeping all cables on one side of the rib but i need to sort this out now its driving me nuts .

Tim M · 30 May 2013, 22:15

Putting the handle back on the other side as it is won't solve anything. I have one of these sat in front of me. I'll take the cover off in the morn and post some photos so it's makes sense. This is a very easy fix!

earthdog1970 · 30 May 2013, 22:25

Ok thanks for that, it would be great if you wouldn't mind.as its hard to work out what i need to do from what everyone is saying .
