A motor that tore off from a speedboat on a lake near Willmar on Sunday caused the boat to submerge and send eight occupants into the water.
The freak incident happened just before 6 p.m. on Big Kandiyohi Lake, with the Kandiyohi County Sheriff's Office reporting that all eight people who were on the boat were pulled out of the water by people on a pontoon who heard their calls for help.
Investigators determined that the 1974 Larson speedboat sustained a major outboard engine malfunction. A 35-year-old Hector man driving the boat was trying to bring the boat up to speed when there was a loud noise from the back of the boat.
That noise was actually the outboard motor tearing off from the transom, which caused the motor and a part of the boat to fall into the lake, resulting in the boat immediately taking on water and beginning to sink.
Four adults and four children were rescued without injuries, fortunately.
The sheriff's office says the age of the boat and excess occupancy weight were factors in the motor ripping off.
Authorities were able to remove all parts of the damaged boat from the lake.
