William "Bill"

H. Mosher

William H. Mosher, 78, of Waterloo, formerly of Lake Mills, passed away at his home on Friday, June 12, 2026.

He was born in Racine, Wisconsin, the son of the late Harold and Lorraine (Schultz) Mosher.

William graduated from Lake Mills High School, attended college and earned an engineering degree. William was later drafted into the United States Marines, from which he received an honorable discharge.

He was employed by DeVor Tool & Die and owned and operated H&M Race Productions. Following retirement, he continued to be a reputable and well-known engine builder throughout Lake Mills and the surrounding communities, generously sharing his knowledge and helping others whenever he could.

A passionate engine builder and drag racing enthusiast, William spent countless nights at the racetrack and dedicated much of his life to the sport he loved. Known for squeezing every bit of performance he could from an engine, he seemed to find a supercharger for nearly every car that came his way. Whether building engines, talking shop, or enjoying a night at the races, he was happiest around horsepower and the people who shared his passion. He loved spending time with his grandchildren, whether it was enjoying Culver's, slurping down milkshakes, or simply being together. He was known for his strong work ethic and the lasting connections he made throughout his life.

Survivors include his two sons, Kyle (Heather) Mosher of Columbus and Jordan (Michelle) Mosher of Waupun; and two grandchildren, Cyrus and Paxton.

William will be greatly missed by those who knew and loved him.

In accordance with William's wishes, no formal public services will be held.
