Great Oak Marina’s Service Department is comprised of certified technicians:

  • Service Facility — Our service facility features include drive-up test tanks designed for outboards and I/Os up to 300 HP. This enables us to quickly provide testing and service when necessary without hoisting your engine off your boat. It also gives us the advantage of testing the total system at one time. With our travel lift and hoist, we are completely equipped to handle all service and repairs, including fiberglassing and engine rebuilding on all sizes of boats. We maintain an extensive parts inventory so you do not have to wait for what you may need in a hurry.

  • Engines and outboards — Evinrude, Yamaha, and Volvo Penta Engines
  • Boats — Four Winns,  Striper Fishing Boats, Cruisers Sports Series
