1989 Johnson GT175 Shifter problem

[jamielenox]

I am looking for help with a (self induced - most likely) fault with my gear shifter on my outboard:
I have just had the carbs off to clean the jets, and on putting it back together I stupidly nipped up the trunions for throttle and gear linkage behind the clamps (I.e. Both about an inch too far back and tightened on the cable - madness I know, I was running out of light...)

The result when I put it in the water to test it was the engine firing up with lots of throttle and then throwing into reverse.

A quick daylight inspection revealed my earlier stupidity and I correctly routed the trunions.

Now I can't select forward or reverse. I've removed the cable and tried operating manually and can just about get reverse but it is beyond the scope of the cable movement.

Have I trashed the dog clutch or is it possible that the misaligned trunion and force from the remote has grossly misaligned the shifter rod?

Any help much appreciated!!

Agreed, best to have a look at the clutch dog.

I expected as much, is the clutch dog and shifter mechanism easy to get at (and service) once the lower unit is removed or is it all pressed into the casing?
Sorry for the basic questions - I am wondering if the path of least resistance is to get a recon lower unit and swap it out.

I am not sure why anyone would want to buy replacement parts without doing a comprehensive inspection first ?

If the clutch dog is pressed into the casing I neither have the tools nor expertise to swap it out - hence my question.
The boat is also in a fairly remote location which I have to access by ferry, and it's stored outside. It is therefore my preference to start and finish a job with everything I need to hand.
If anyone can answer the question reference the gear casing and shifter mechanism I would be very grateful.

You need to remove the propshaft bearing housing first.----Then remove some very large snap rings.----Then remove reverse gear to inspect clutch dog.-----The clutch dog slides on the propshaft.-----In order to replace the clutch dog the lower unit MUST come off and the driveshaft has to be removed.---Then propshaft has to be removed.----A manual would surely help you.

When you're trying to select manually is the motor running or are you turning the prop by hand or foot?
That could take care of the manual shifting then if the cable doesn't have enough travel it may be a problem in the controller or adjustment.

Fed,
I've tried it with the motor running - I'm convinced the issue is not with the controller as it appears to have a fairly healthy throw on it. Thanks for the page from the manual - the one I have is not very clear.
I think it's a lower unit off job - I was clinging to the hope that I had misaligned something which could be rectified without taking it all apart....
Wishful thinking!
