Forward = Reverse and Reverse = Reverse

[superfets]

Hi all, thanks again for all your help.

So I hit a rock and put a hole in the front of my alpha one gen 1. I still managed to drive 20 miles back to the cabin. And then another 10 mile to a boat launch get it home. It still worked like normal but sure sounded rough.

At home I took the whole out drive off the boat. Split the upper and lower. Didn't find any problems in the upper. So got a used lower. Installed a new impeller. Re-installed it. When I re-assembled it I made sure the washer was in place. Made sure that the shift gear was in forward by turning it clockwise with my hand and the turning the prop shaft counterclockwise and feeling that it was fully engaged. And when I mated the two back together I made sure the other majiger was lined up straight so that it would line up the other majiger with the throttle in forward when i re-installed the two halfs onto the boat.
Are you getting what I'm laying down. Then in the driveway on muffs I ran it. Shifted in to forward and the prop turned. Then shifted into reverse and the prop turned again. Back into neutral and the prop stopped turning.
Now today I put it in the water and only have reverse. I move the throttle into forward but the boat goes backwards. I shift the throttle into Reverse and the boat still goes backwards.
The one thing that came to mind as I'm writing this is that I didn't put the shift leaver into forward when I first took it apart.

Ok people. Please share your wisdom with me. Any and all thoughts are very much appreciated.

Thanks again.
Stef

probably when you installed the drive the roller in the arm did not engage the fork in the slide. and is behind the fork. Reverse is a pulling action, fwd is a pushing action

Ok Bt Doctur, have a look at the pictures. I did manage to get the fork in the slide, but i think i may have missed forward by a tooth or something when i put the upper and lower back together. And it looks like the shift leaver on the outdrive could be a 1/16" of an inch higher so it would mate up better with the gimble side of the shift leaver. What are your thoughts?

Thanks again,
Stef

The first 3 pictures above were taken with the drive still attached. Looking from the bow towards the stern. I really don't like the way the fitment is between the shift shaft on the bell housing and the outdrive. With the outdrive off there is some up and down play on the shift shaft. I'm going to split the 2 and see what it takes to raise the shift shaft in the outdrive.

But for the life of me i can't see why it was going in reverse in the water yesterday.

Now with the out drive on the bench, if i have the shift shaft lined up straight bow to stern, or at 12 oclock looking down from the stern, and turn the the drive shaft counter clockwise the prop will turn clock wise. i now move the shift shaft (looking down from the stern) from 12 o'clock to 11 o'clock, were in neutral, and the turn it to 10 o'clock, still turning the drive shaft in a counter clockwise rotation, the prop now also turns counter clockwise.

And as you can see, when i pulled the outdrive an inch away from the bell housing. The slide is clearly in the fork. I'm completely dumbfounded.

I have no idea why it was going in reverse.

Anyway. once i get the shift shaft to sit a little higher and everything put back together and in the water again i will report back.

And please comment on what you thing may have happened, did i miss something?

thanks again,
Stef

If you have installed the SS washer in the lower splined shift shaft and the upper shoe is not inserted almost all the way them I`m guessing you may have tried to draw the 2 units together with the nuts. This resulted in bending the "C" selector in the lower unit. With the lower splined shaft turned fully clockwise the prop locks CCW. The lower unit drive shaft turns clockwise
