    Possible Cone Clutch Failure???

    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.

    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

    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.

    Also, I did put in gear and prop only spun 1 way.
    Both forward and reverse.
    Spun free in neutral

    I would try a prop if you have one never seen a solas spin a hub but ya never know then drop the oil in the drive and see what it looks like

    The Solas is relatively new to this boat. It ran great on there for a month.
    I still get the typical clunk when I put into gear in reverse. I do not get the clunk in forward even though the prop does turn when I put into gear.

    still sounds like the the shift flange is not moving far enough to engage the gears in fwd I adjusted mine on the trailer with the wife at the controls you don't need the prop or the motor running remove the shift cover and cable then test.

    page 64 on is about the shifter

    Ok, well I am going to pull the boat today. Quite a long tow.

    Does it make sense tho that it worked perfectly fine for a month with no sign of anything like this happening?
    The shift mechanism is where I am going to start, but what exactly am I looking for when I pull it? Will it be obvious?

    Thanks Matty

    yes it could be fine one day and out of whack the next before you tear the drive open you need to inspect the cable and connections. if the cable ends are not secured the cable will not move correctly. they are locked into the shifter and the outside of the volvo drive the clamp that holds the cable onto the drive could have come loose . you need to look at it while you move the shifter flange you will hear it and feel it engage in gear by hand. the holes in the ears of the flange are at 5 and 11 oclock if you turn it to the right all the way and are at 2 and 7 oclock if you turn it to the left all the way. and again you will see it pop out except in neutral

    if it were a upper drive problem I would imagine you would have other signs like noises and metal on metal
