Merc "Quicksilver" Shift Control Box Issue

[Carolina Pearl]

Can use some helpful advise folks!
I have to adjust the "gear shift throw" on the linkage of my Quicksilver Controller, 85 Merc 150 XR2, 84 Ranger 350V.

It shifts fine going into reverse, but is a little rough going into forward, unless I rev the motor a few RPMs which I do not care to do.

I am 99% sure the adjustment needs to be made at the controller box location, which is mounted inside the hull. I have already checked the adjustment on the motor head and with the linkage disconnected, it shifts fine into both forward and reverse.

QUESTION?
How the h..l does one remove the control lever from the control box so they can adjust the linkage on the control box located inside the hull?

The lever is lose on the spline which I can jiggle, but I can not for the life of me figure out how to remove it.

All knowledge and experiences are appreciated!

Thanks

Under the handle there is a set screw.
The bottom center of the loose part.

There is no adjustments in the box, just cams and levers. The adjustments are on the cables at engine.

Thanks to all the replies!

Yes, one can see in the 3 pics above the box is mounted behind the interior hull wall. I am leaning to believe that the shift cable has loosened up and is sliding a bit on the box end. A previous owner installed a Hot Foot in the boat at one time and may have reinstalled the box improperly with the shift cable not securely tightened after the Hot Foot application.

Will let you all know what I find soon...

Well, that kinda sucks then, sounds like the clutch gear in the lower unit of the transmission then...

You are not paying attention. Cable adjustments are on the engine -- not in the lower uinit.
1) Remove the engine cover.
2) Locate the two cables (throttle and shift.)
3) Put control box lever in NEUTRAL.
4) Disconnect both cables (Note which is which).
5) Ensure throttle/shift lever is in NEUTRAL (Yes - again).
6) Move the lever ON THE ENGINE to verify it is in NEUTRAL
7) Bring the attachment point on the cable end up to the attachment point on the engine shift lever. DO NOT push or pull or attempt to connect it. If the two points don't line up exactly, adjust the trunion (the threaded barrel) until they do. Attach the cable.
8) Repeat the process for the throttle cable holding the throttle against the idle stop.

Thats all the adjustment there is.

I know about the adjustments under the motor covers, Been there, Done that! I know it is not in the linkage adjustment on the power head.

Are there not 2 nuts on each cable at the box end where the cables go into the box?

One nut should be on the inside of the box and one on the outside of the box on each cable to keep them secure so they do not slip on the box when moving the lever???????

I do not have a throttle cable going to the box because I have a HOT FOOT installed. But, I do have free play in the shifter cable when moving it to the forward position. No play when shifting into reverse

Now, who is not paying attention? LOL!

If the shift cable has a threaded end at the
motor with a adaptor screwed on then
the control box will look the same and
can be adjusted. If it's a mercury cable,
Then no adjustment. But when it's apart
you can check for worn or loose parts.
Also check the cable for wear, to much
end to end play.

OK, that's what I am hoping for!

In an earlier response, you mentioned:
"Under the handle there is a set screw. The bottom center of the loose part"

Now, do you mean on the bottom of the lever in the spline shaft area and what did you mean by "loose part"?

Is the set screw visible or hidden?

I had no luck in locating a set screw around any part of the handle which mounts on the spline...

Thanks

Re: Merc "Quicksilver" Shift Control Box Issue

I called it the loose part because you said it
jiggled on the splines?
The set screw is in the shift handle bottom
and runs up into the splines.
6 o'clock position.
Put the shift lever full forward it will
be easer to see. 3 o'clock position.

Very Good!
Hope to find it this time..
Thank you so much and will let you know how I make out!

Re: Merc "Quicksilver" Shift Control Box Issue

Finally found the set screw and after moving the handle as suggested. The trick was to turn the mounting bracket also until it lined up with a groove to get to the set screw. Haven't moved the box yet to work on it, but I could see one cable was sitting at a different position than the other in the forward shift location.

Thanks to all!
