About Us


Tinus Marine is a family tradition of quality boat sales and service for 69 years.

Our family boating history started with Harold Tinus, and his passion for boats. He grew up on Oconomowoc Lake, tinkering with his friend's boats, friends such as Pabst, Miller.......racing Miss High Life. When he married Arlene Onasch, he had a day job delivering milk, but his passion remained with his night job, in his garage, repairing and refinishing boats. In 1948 Tinus Marine was incorporated and with the help of Augie Pabst, the Mercury franchise was purchased in 1950. Harold and Arlene's sons Steve & Tim now run the show and the 3rd generation, their sons are becoming an integral part of the family business.

When you become a customer of Tinus Marine, you become part of a long line of boaters, one big family that shares a passion for owning the best boats on the water!

Sales Manager Tim Tinus

"We Only sell boats that we would put our families in. Quality is not only in the materials, but in the design, construction and safety features included in all our boat lines. The boats we sell are lines we have researched and used ourselves. We trust the manufacturer, many of which are family businesses such as ours."
