    Does anyone have any direct experience with VOLVO "DUO-PROP" 
    I am considering buying a new 21' boat and it has a 5.0 engine
    with this "DUO-PROP" I/O.   
    
    I've seen the marketing info, but I'm conserned about the reliability
    of it.
    
    Any info would be appreicated.

|     I have come across alot of the Duo-prop's..They tend to give just a tad
    more performance, and are very reliable. The real advantage the folks
    that have them tell me is in maneuverability at slower speeds and 
    docking. It seems the twin props tend to defeat the normal torque
    characteristics of the single prop units. They have been around for
    quite some time..

|     i have one on my 1991 chaparral. see note 387.4.   you should really
    check out the 4.3l v-6 with 205hp.  it's lighter than the 5.0l v-8 and
    has more horsepower.  i love the duo-prop.   i was beside a sea -rea
    seville with a single prop and we both hit it at the same time.  i was
    on plane within seconds and he took very long to get up.  both of us
    had 4 people on board and mine was only one hour old. however, there are
    no after market props available and when you bend one you often bend two! 
    this is supposedly a very reliable outdrive.  the new ones shift quieter
    than the original ones, but the older ones had no reliability problems.

|     I have no first hand info but when talking with a mechanic during
    on of my many cobra rebuilds he had nothing but good things to say
    about volvo outdrives.
