If the shift rod can not go down all the way the propshaft will not come out.-----The damage makes it obvious to me that brute force is needed.-----Sorry to be blunt.----And I am not struggling to work on these simple ( to me ) gearcases.

Yeah , but how much brute force ,I mean dont beat the crap outa it but maybe give it a few taps ......to start with 😀 who knows , maybe you could see a bit of broken ally on the front of the gearcase pop out and the thing will drop into reverse.
Some peeps like doing stuff like this even if its not financially worth it from a business point of view. There is satisfaction in getting to the bottom of the issue..........its like growing your own vegetables instead of buying them ,its not a money thing .
It must go on there because I have been pleasantly surprised how many of you are running older motors because you like older motors . After completing a resto/ rebuild yourself you have something to be proud of but if you just buy a motor all you have is a motor.🙂

Ya I think I’m gonna start cutting, delicately, into the case if nothing else just to see whats fu**ed up. Ya never know I might be able to save it. Or maybe save the guts, get a new prop shaft and maybe find an empty gear case? Either way, the boat is wrapped up again as if we’re coming into winter. It might be a month or 2 before I get it fixed. I gotta see how the tax man bends me over this year!

There is NOTHING you can do from the outside of this SCRAP gearcase to make the shift rod go down all the way.----See post #2

Yes Jim I think cutting carefully from the OUTSIDE of your not total SCRAP gearcase is a good plan ,and sussing out just what is not damaged . Just coz some smartypants tells you its scrap aint nessessarily true and anyhow us real mechanics like to find out for ourselves where as some others prefer to remain ignorant. There is no substitute for experiencing stuff personally, its the whole essence of gaining knowledge . This is a lot of whats wrong with the world today , we get youngsters with letters after their names ,cradle marks still on their arses getting important jobs but they have little or no actual hands on experience . I love putting them in their place when needed😀

It is SCRAP !----And I started repairing outboards in 1968.-----Have also worked on steam turbines that produced around 1,000,000 HP.

I think it’s pretty much an anchor. An expensive one at that! LOL But my curiosity is satisfied. I know what makes it work…. And not work. TBH I’m sure I could fix it, but add up the cost, ( prop shaft alone is $675) and all the work/time, it’s just not worth it. Add in that in the back of my mind I would always be worried that it might fail on me. Once a year we go to Dworshack reservoir for the trophy smallies, and we go up lake about 8 miles or so. There are no boat ramps or much up that way. So if we were to have a problem, that would be a big PROBLEM! We usually go mid/late May. IDK if we’re going to make it this year.

i believe the etec 40-60hp motors used the same gearcase as a 50-70hp 3 cyl 1989-up but not sure if the driveshaft is the same. just food for thought. you;d need to compare part #'s.

That’s interesting. My neighbor has a 60hp that the motor is shot. It’s an early 90s Johnson VRO

I picked up this motor from my neighbor. The gear case is identical to mine. Except it doesn’t have a gaping hole in it. LOL From a quick look I can see that the shifter rod will have to swapped. This one has an offset at the top that the e-tec one doesn’t have. I’m going to cross check part numbers for the F and R gears and stuff. I will tear into this one go thru it and check it out. See if anything needs replacement.

You will likely have to swap driveshaft as its fine spline. Most of the 60-70hp 3 cylinder where 4 spline. If you swap shafts you will need to reshim pinion

This was a running motor a few years ago. I re-did the carbs on it for him. But a year or so later the motor was pretty much a dead dog. It ran, not very well tho. The #1 cyl is way down on compression. Anyway he took it off and purchased a new 60hp Merc. He said that it was stubborn going into R also. Since I'm going to have it apart to swap the driveshaft and such, I should remedy that issue too.

Gear ratio is different between a 1990 model and much newer motors.-----You have to be very careful when swapping newer parts into an older gearcase.----Model # on the motor that hit the rock.-----I tell folks that a GPS unit to tell you where the rocks might be is very cheap !!!

looks like the parts motor you have MIGHT work as its a fine spline (last year of older style trim pretty interesting). as you said swap shift shafts and see if it will work. it is very possible the driveshaft is too thick though. i feel like ive compared the 2 driveshafts once and the 3 cyl ones had a slightly different taper at the bottom underneath the bearing housing, possibly making the pinion height messed up if you swap your etec driveshaft. nothing to loose at this point though to atleast try. as mentioned shimming is necessary not optional if you get that far!

I can and will measure the drive shaft and also compare to the old one. the old busted prop fits on the prop shaft on the white unit. So, that's a plus. Also, the blue unit (the broken one) has 2 alignment dowels where it bolts up the motor. The white unit doesn't have any. And the holes aren't big enough to accept the dowels. Should I drill those to make em fit, if I get that far? And how critical is shimming the pinion? As you said, at this point it's worth a try. I could pay the $2600 tomorrow for a refurbed unit, but, I got other things that I need that $$$ for. Like a 28x40 concrete pad that I've just been waiting for the weather. And it's almost time!!!
