Outboard Maintenance
Service, repairs, and repowers from a Mercury Repower Center and Minn Kota Authorized Service Center with master and certified mechanics
Mercury Outboard Service
As a Mercury Repower Center and a Minn Kota Authorized Service Center, our service department maintains, repairs, and repowers Mercury outboards, from portable kickers to high horsepower engines, and services Minn Kota trolling motors year round.
Routine maintenance keeps an outboard starting easily, running cool, and holding its value. We change oil and gear lube, replace spark plugs and fuel filters, inspect water pumps and thermostats, check anodes, and grease steering and tilt points. When something is wrong, we diagnose rough idle, hard starting, overheating alarms, loss of power, and trim problems. When an older engine is no longer worth repairing, we can repower your boat with a new Mercury outboard and rig it for your hull. Other dealerships often call on our mechanics for difficult diagnostic work, and later appointments are available by request.

Our Maintenance Process
Every outboard goes through the same five steps, so you always know where your engine stands.
Tell Us About Your Engine
Share your engine model, approximate hours, and anything you have noticed, like hard starting, vibration, or an alarm on the water.
Check In And Inspection
We log your engine hours, look over the lower unit, propeller, and fuel system, and confirm the service your engine is due for.
Estimate Before Extra Work
If we find something beyond the service you requested, we contact you with an estimate before any additional work begins.
Service And Testing
Our mechanics complete the work to the manufacturer schedule, then run the engine to confirm it starts, idles, and cools properly.
Pickup And Service Notes
When your boat is ready, we walk you through what was done and anything to keep an eye on next season.
