Hey guys need some serious help here I am smashing my head of the wall on this one...

So I'll start my story went out for a troll on lake ontario and my 9.5 would not push my boat past 2 mph witch it did before so I checked for spark and only firing on one cylinder. Got the coils don't fired first pull woohoo didn't look like it was pushing alot of water been a few years so change the impeller.. I pulled the drive shaft out to change the plate under the impeller

And now the problem when I got it all back together linkage all lined up with grooves and fired it up will only go into reverse and a pain to get it into neutral... the crap situation is that it worked fine till I changed the impeller...

Any help would be great I am stumped
 
They are lined up with the groove on both ends of the shafts that was the first thing I checked thought I might have missed but nope all lined up
 
If the shifting was normal before you took it apart... And You Did Not... take anything else apart...... ??
I know of nothing else that could screw up the shifting automatically.
 
The driveshaft slides out of the pinion and slides back in.------The driveshaft is NOT your issue.--------Worked on many of these and I would first check at the brass coupler as already mentioned to you !!
 
No did not open the lower unit at all just the drive shaft fell out when I lifted the impeller housing off and now will only go into reverse and neutral when I put it in the forward position
 
Did you start it and try shifting? You need to spin the prop while shifting if the engine is not running to line up the dog into the gear?
 
Did you change the gearoil? If you pulled the phillips head screw you may need to take it apart to get the pin back into the shift fork.
 
I will change gear oil tonite when I get home from work and no I did not pull the pin out part number 23 could that be broke and make this happin

Part #23 is correct.... No, impossible for it to break. Unless you have a fair amount of play in that upper shift rod suddenly for some unknown reason that did not exist previously... I'm still locked into the brass shift connector no being aligned properly.
 
Should I push the upper past the groove in it as it looks to be beveled about 3/4 inch higher then the groove I have it in now
 
No the upper shift rod and the lower shift rod have a notch.-----That notch is to be lined up with the hole in the brass connector BEFORE you install the fine threaded bolt !!!

Push the rod "past" the groove? Only if you want to destroy the brass connector and the fine threaded bolt! However... there is no way you could possibly shove the upper rod into that brass connector 3/4" without shoving the bottom shift rod out.... and even if you could without moving the bottom shift rod, you wouldn't be able to insert and/or tighten the connector bolts. There's barely enough room as is!

Frankly, with the combined knowledge that is available on this site of the Evinrude and Johnson engines through the years from day one to the present.... what you are coming across with is impossible and strongly suggests that you actually don't have this engine or its problem but rather you're playing a game and wasting our time.

I'm outta here!

The bolts in the connector should locate in the cut outs in the shift rods.

You should have only removed the lower bolt.

Read the section in your workshop manual that describes reconnecting the shift rods.

This diagram shows how the lower bolt should be refitted. The upper bolt should be similar
