Expert Repairs Backed by Certification

Being a certified dealer means more than just having access to parts—it means we’ve met the highest standards in training, tooling, and service quality. Our technicians are certified and up-to-date on the latest diagnostic procedures, repair techniques, and product updates from the leading names in marine power.

Whether you operate a high-performance outboard or a dependable inboard system, we offer tailored services to keep your engine running at peak performance.

Comprehensive Engine Services

At WOT Marine, we handle everything from small tune-ups to complex diagnostics and repowers. Here’s what we offer:

✅ 100-Hour and 300-Hour Scheduled Maintenance

Routine maintenance is the key to long engine life and reliable performance. Our service packages include:

• Oil and filter changes

• Fuel filter replacement

• Gear lube replacement

• Complete engine inspection

These scheduled services are designed to catch potential problems early and keep your engine running efficiently through every season.

Clean fuel systems mean better efficiency, smoother operation, and fewer breakdowns.

Our team uses diagnostic tools to locate faults quickly, ensuring your electronics, starting systems, and onboard equipment all work reliably.

As a certified Mercury service center, we’re authorized to handle warranty repairs using genuine OEM parts. That means:

• Factory-approved components

• Full compatibility and performance

• Backed by manufacturer warranties

You’ll get peace of mind knowing that every repair meets the standards set by the engine manufacturer.
