    a friend of mine has water coming out of the spark plugs and the moter will only run on full choke is it a cracked head?

    or what?
     
  2. Could be a cracked head or head gasket.

    I had the same problem and it was a head gasket on my 25hp. Good luck with it.
     
  4. or a busted exhaust manifold or gasket

    What kind of motor? Big difference between an outboard and an I/O.

    Bad head gasket, cracked head or block... until it's torn apart, hard to say.
