Possible Cone Clutch Failure???

[Gerk]

I am having an issue with my Volvo AQ 280. Hopefully someone can chime in before I completely tear apart my drive.

Lately I have been going out and it will go in and out of gear just fine.
After a little driving, it will not go into forward. It goes into reverse just fine. No prob.
Sometimes I will shift it into forward 1 click and it will eventually go, but not all the time.
Now, I am not getting it to go at all in forward. Had to slowly make my way home yesterday in reverse.(not too far)

There is oil on the dip stick, no milky oil.
The linkage is working so it is not that.

I did lift the drive up and put it in gear to see if I could see something and the prop does spin, but slowly. Not enough to drive the boat and maneuver.

Any tips before I tear into this?
Does it sound like cone clutch/sliding sleeve?

Thanks all

Remove the cover plate on the upper half of the drive, and make sure the shift cable connection is secure.

You can also manually move the actual shift mechanism lever and see if the drive goes into/out of gear.

Yep, I did that.
Very secure and it goes all the way and no real engagement

Yep, I did that.

remove the cable and linkage and manually move the shift flange( looks like a bow tie) the flange should retract in neutral and should pop out in either R or F with the cable off you will get the most deflection either way. take the prop off and shift manually then try and turn the prop shaft either way N will spin boths way F and R will turn one but not the other

and remember what side the cable and linkage was on or backwards you will be .

had this issue it was a bad shift cable

[Gerk]

OK I can try again.
I did test it with the cable still on. I suppose it could still go more. I thought it was all the way, but who knows.
Tough to do on the buoy.
Hopefully that will do it.

If not, does it sound like a cone clutch issue?

Ok so I removed cable and put in and out of gear forward and reverse.
Does the same thing. Engages in reverse real good and hard. Engages in forward but only very minor. Even giving it throttle does not push the boat.
The prop does spin, but not like normal.
