    "suspect the clamp came off"  better go check it. if thats the 
    case aren't you discharging exhaust into the boat?
    
    best check out what is the problem.......

    In addition to the exhaust problem that Jim mentioned, it's also
    possible that the open exhaust hole in the transom could allow
    water to pour in.  This can lead to a condition where the boat
    comes to rest on the bottom of the lake, and should be avoided
    if at all possible.  8^)
    
    Bottom line, don't drive the boat until the exhaust is reconnected.

      On that outdrive there is a 3" rubber hose between the exhaust
    manifold and the start(for want of a better word) of the outdrive.
    Once the exhaust enters the outdrive, it only goes through aluminum
    until right at the base(of the outdrive where it passes through
    the transom) where there is a flare of rubber to disperse
    the exhaust. (one on each side)
    
       If you are seeing water "splashing" around I would think that
    something is BROKEN. The big exhaust hose is a really short piece
    that is *inside* the boat. Any "splashing" outside the boat that
    wasn't there before doesn't sound good at all. I think you need
    to find out exactly WHAT is causing this "splashing" before you
    can even *think* about using the boat. 
    
       Also if any part of the exhaust is broken, you should hear a
    louder than normal exhaust note.

    re .2   I AGREE !!!!!!!!!!
    
     DO check things out carfully !!!   I SPEAK from experience
    ...unfortunatly. Boats do sink!!!! and mine DID when the bellows went
    bad!!!  What a drag !!!!

    In the Volvo Penta outdrive, there is actually 3 hoses exiting thru
    the transom relating to exhaust. The exhaust route is thru the exhaust
    manifolds(attached to the engine) to a "Y" shaped plenum which has
    an approximately 3 inch outlet dead center in the transom: from
    this outlet a rubber flexible "exhaust bellows" connects to the
    outdrive where the gases go thru the outdrive and exit above the
    prop fron the anticavitation plate. There is also 2 hoses approximately
    1 inch in diameter that also exit thru the transom(1 on either side
    of the larger 3 in exhaust "port") that are connected to the "Y"
    shaped plenum. The plenums internal design separates much of the
    water from the exhaust and it is thru these SMALLER hose outlets
    most of the cooling water is expelled. Sooo__ you could conceiveable
    see SOME bubbling/activity in this area and NOT have a problem.
      However if you see a LOT of bubbling and exhaust gas coming from
    this area, as you suspected the "exhaust bellows"hose has probably
    slipped off the transom outlet or the outdrive inlet. In either
    case, it is not critical (other than the fact that the hose may
    eventually fall off altogether at the cost of approx. $40.00 for
    the replacement) as long as you realize that with this hose off
    a BIG wake hitting you on the transom or if you are backing down
    HARD ,the water COULD be forced back up the plenum where it MIGHT
    enter the exhaust manifold and be forced thru the engine exhaust
    port into the cylinder. We know what can happen at that point !!
    That is why some VOLVO PENTA outdrives use a rubber flap on the
    outlet on the cavitation plate and other VP outdrives (possibly
    older models ) use a pivoting flap INSIDE the "exhaust bellows"
    hose. Sorry to make this long-winded: just wanted to clarify what
    my 280 outdrive is setup like (yours SHOULD be similar) and I also
    ran for half a season with my "exhaust bellows" missing and had
    no ill effects.

    Many thanks for the suggestions.  I decided to play it safe and not
    use it until it was checked out.  The problem was with one of the
    2 small hoses that Ron described in the previous reply:

    "There is also 2 hoses approximately 1 inch in diameter that also exit 
    thru the transom(1 on either side of the larger 3 in exhaust "port") that 
    are connected to the "Y" shaped plenum. The plenums internal design 
    separates much of the water from the exhaust and it is thru these SMALLER 
    hose outlets most of the cooling water is expelled."

    One of the hoses had a tear at the end that redirected the cooling water
    toward the transom and increased the splashing.  This is only an
    annoyance and I can live with it for now and fix it in the fall.
