RedactedNarrative: A 24 foot cabin motorboat with four people and two dogs aboard was leaving Dagmar's Marina enroute to Hat Island on the Snohomish River, west of SR 529.  Shortly after departing, the operator noticed the boat was not handling properly, then the engine quit and the boat began filling with water.  The Snohomish County Sheriff's Office responded to a call about a sinking boat and got everyone off the sinking vessel onto their boat.  All people on the vessel were wearing life jackets and there was no evidence of alcohol use reported.  There were no injuries.
  
  The partially submerged vessel was towed to Dagmar's Marina and during the tow it began to list severely to port.  At Dagmar's marina it was de-watered and removed from the water.
  
  The owner reported that she had service work done on the vessel at Dagmar's Marina prior to the trip.  A Dagmar's representative told Snohomish County Sheriff's Office investigating officer that the boat took on water because someone neglected to re-install some drain plugs.  Staff at Dagmar's said they would figure out how it happened to learn who was responsible.
