RedactedNarrative: Operator #1 Stated: "We were leaving.  Heard a snap/bang. Lost power." 
  
  Investigation Reveals:  Vessel #1 was departing from Tices Shoal.  Same was transiting in a NW direction.  Vessel #1's starboard outdrive struck an unknown underwater submerged object/ bottom.  As a result of the impact, Vessel #1's starboard outdrive housing cracked/detached from the stern.  Due to the outdrive becoming detached, Vessel #1's water tight integrity was compromised, allowing water to enter and flood the bilge of the same.Vessel #1 came to a tp in an area with approximately 2.5 to 3  feet of water depth. Sea Tow responded and was able to plug the breach temporarily, as well as pump water out of the bilge, to float same. Sea Tow then Towed the vessel to Holiday Harbor Marina.
