STO Boats was built from real time behind wake and surf boats - not dealership programs or general marine repair. We grew up waterskiing, wakeboarding, and wakesurfing, spending thousands of hours driving, adjusting ballast, selecting props, tuning surf systems, and learning how these boats are meant to perform when set up correctly.

Today, we service, tune, restore, and dial modern wake and surf boats with a performance-first mindset. These boats should do more than just run - they should pull clean, push hard, and deliver a ride that makes time on the water worth it.

OUR EXPERTISE

Wake and surf boats are not standard boats.

They require precise setup - ballast calibration, surf system tuning, prop selection, speed control, drivetrain balance, and electronic integration.

Most marine shops service everything.
We focus exclusively on modern inboard wake, surf, and performance boats.

We specialize in modern inboard platforms powered by PCM, Ilmor, Indmar and Mercury.

Our work covers:

Engine & Drivetrain
• Diagnostics and troubleshooting
• PCM, Ilmor, Indmar, Mercury engines
• Prop selection and drivetrain allignment

Surf & Wake Systems
• Custom ballast installs and plumbing
• OEM and custom Surf systems installs
• Wave optimization and performance setup

Electrical & Control Systems
• Wiring diagnostics
• Pumps, switches, PDM, charging systems
• Control modules and integration

From routine service to full system troubleshooting,
we approach every boat as a performance platform - not just a repair job.

WHAT SETS US APART

• Inboard-focused service using OEM parts with direct manufacturer access
• Large in-stock inventory of engine, ballast, and drivetrain components
• 7,000+ hours of real on-water experience
• Performance diagnostics and system-level tuning
• Dockside mobile support - no marina delays
• Trusted by Nautique, Malibu, Axis, Centurion, MasterCraft, Supreme, and Tige owners

When your boat leaves STO Boats, it isn’t just repaired.
It’s dialed in.

STO Boats founder with Nautique Paragon 25 and Paragon 23 wake and surf boats in Ontario shop

“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 club and competition boats, running new Correct Craft and Centurion models each season. Setting ballast. Dialing wakes. Changing props. 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.”
