Eight people were rescued after their boat sank in Big Kandiyohi Lake in west-central Minnesota.

The Kandiyohi County sheriff’s office said authorities received a call just before 6 p.m. Sunday of a submerged boat. Everyone who was in the water was pulled to safety by others on a pontoon who heard the calls for help.

The driver of the 1974 Larsen speedboat, a 35-year-old man, was trying to bring the boat up to speed when there was a loud noise at the rear of the boat.

The outboard motor tore off from the transom. The motor and a portion of the boat fell into the lake, according to the sheriff’s office. At the time, the driver, three other adults and four children were aboard all of them were rescued and none were injured.

The lake is located 25 miles South of Willmar, Minnesota.
