STO Boats was built around modern wake and surf boats.
Not general marine repair. Not dealership after-service. Precision service and system-level tuning for boats that demand it. Wake and surf platforms are integrated systems - ballast, tabs, engine, electronics, audio and software working together. We service and tune them as performance systems, not just boats.




STO Boats operates from a dedicated service facility in Innisfil, Ontario - equipped for diagnostics, engine and driveline work, electrical systems, surf setup, and seasonal storage.
We also provide dockside mobile service across Lake Simcoe, Muskoka, Georgian Bay, and surrounding regions.

"I didn’t get into wake boats through service. I grew up in them. My story started in 1999 behind a Malibu Response. Riding. Driving. Learning. For years I drove wakesurf club boats and competition boats.
Every season we ran new Correct Craft and Centurion models.
1,000+ hours a year. Over 7,000 hours behind the wheel. Setting ballast. Dialing surf tabs. Changing props. Driving contests. Managing crews. When you spend that much time on the water, you learn how a wake boat is supposed to feel. That’s where STO Boats comes from. Not dealership after-service. Not general marine repair. Wake and surf boats. Set up properly."
