Complete Outboard Motor Services

Outboard Tune-Up & Preventative Maintenance
Routine maintenance keeps your outboard engine in peak condition and helps prevent costly breakdowns. Our tune-up service includes:
- Oil and filter changes
- Spark plug inspection and replacement
- Fuel and air filter replacement
- Compression tests
- Complete system inspection
We recommend regular service intervals based on your motor’s age, hours, and usage. Whether you're running a Yamaha 150 or a Mercury Pro XS, we’ll help you maintain long-term performance.

Outboard Diagnostics & Electrical Repair
Modern outboards rely on complex electrical and sensor systems. If your motor is hard to start, losing power, or giving warning codes, our team provides:
- Full-system electrical diagnostics
- Battery, alternator, and charging system testing
- Ignition, wiring, and sensor repair
- Trim and tilt troubleshooting
From basic wiring fixes to full system rewiring, we’ll track down the issue and get your motor running right.

Lower Unit Service & Repair
Lower unit damage can lead to serious performance issues or complete motor failure. We provide:
- Propeller shaft repair
- Gear replacement
- Seal and bearing replacement
- Pressure testing
- Complete lower unit replacement (if needed)
If your gearcase is leaking oil, making noise, or not shifting properly, we’ll evaluate it and offer the best long-term fix.

Powerhead Rebuilds & Engine Overhaul
When compression drops or major damage occurs, rebuilding your outboard’s powerhead may be more cost-effective than replacing the entire motor. Our engine rebuild services include:
- Cylinder inspection and honing
- Piston and ring replacement
- Crankshaft and connecting rod servicing
- Gasket kits and resealing
- Full reassembly and test-run
We handle complete rebuilds in-house and provide straight answers about whether it’s worth rebuilding or replacing.

Fuel System Repair & Injector Cleaning
Poor fuel flow can cause hesitation, misfires, and poor fuel economy. We service:
- Clogged or dirty fuel injectors
- Carburetor rebuilds and cleaning
- Fuel pump replacement
- Fuel line and filter replacement
We also offer outboard carburetor cleaning and fuel system flushes to restore smooth operation and reliability.

Cooling System Repair
Overheating is one of the most common and dangerous problems for outboard motors. If you’ve noticed high temp warnings or water flow issues, we provide:
- Impeller and water pump replacement
- Thermostat testing and replacement
- Cooling line inspections
- Blockage removal
If your motor isn’t peeing or runs hot at idle, let us inspect it before it causes major damage.

Complete Outboard Rebuilds
For older engines with internal wear or major failure, we offer full outboard rebuilds. These are often more affordable than new replacements and allow you to extend the life of your current boat setup. We’ll assess the cost-benefit and walk you through the process clearly.

Custom Engine Performance Builds
Want more speed, torque, or power? We offer custom outboard builds for serious anglers, racers, and performance enthusiasts. We’ll help design a build that matches your hull, load, and goals—and install it with precision.
