Marine Engine Tune-Up
A real tune-up restores power, smooths idle, and improves fuel economy. If your engine feels sluggish, runs rough, or just doesn't pull the way it used to — a proper tune-up addresses the systems that actually affect performance.
What's Included in a Marine Tune-Up
A real tune-up touches every system that affects how your engine runs — not just a plug swap.
- Spark plug replacement with OEM-specified plugs
- Fuel filter and water-separator replacement
- Carburetor or injector inspection and cleaning
- Timing and idle speed adjustment
- Compression test across all cylinders
- Throttle and shift linkage inspection
- Full test run and performance verification
