History of Engine Machine & Supply

Engine Machine & Supply is a family-owned business started in 1977 by Charles Slater and now operated by his son, Mark Slater and daughter, Joye Josten. Engine Machine & Supply (EMS) originated in San Diego, CA, where engine rebuilding and parts were in great demand. EMS has a long, successful history of work on car and truck engines of all types, plus engines from the tuna fleet.

EMS has continued to flourish, bringing with it a significant amount of high tech machining services which had previously been unavailable in Bozeman.

Engine Machine & Supply is a well known name in the engine rebuilding and parts industry. Mark and Joye have carried on the tradition of quality workmanship and the sound business practices set forth by their father. For the past 28 years, EMS has stayed on top of the rapidly changing industry and is proud to offer new services to better meet the demands of today.
shop interior Joye and Mark are a great team at Engine Machine & Supply. Joye knows the parts and pricing inside and out, and she can get you information on the spot. She also manages the financial side of the business and keeps the inventory current. Mark heads up the shop and the actual rebuilding process. He is a master machinist and oversees the onsite work as well as helping customers.

When not at the shop, Joye spends her time with her family. Mark is an avid runner and he likes to put in a healthy 40+ miles/week training for such events as area marathons, ridge runs, etc. He also enjoys his family time with his wife and children. Both Joye and Mark love living in Montana. It's a great place to work as well as raise a family.
