Routine impeller replacement is critical for maintaining cooling performance and preventing overheating.
Faulty thermostats or blocked cooling passages can cause inconsistent operating temperatures and overheating alarms.
Marine environments cause corrosion inside connectors, grounds, fuse holders, and battery cables that lead to intermittent electrical issues.
Water, ethanol-related fuel degradation, and debris inside the fuel system can reduce engine performance and reliability.
Weak batteries, poor cable connections, or charging problems often result in slow cranking or no-start conditions.
Tohatsu warning systems monitor oil pressure, engine temperature, charging voltage, and other critical systems. We diagnose the source instead of simply clearing alarms.
Rough idle, stalling around docks, or hesitation during acceleration may indicate fuel, ignition, sensor, or air intake problems.
Damaged props, worn hubs, bent shafts, or engine mounting issues can create vibration and poor handling.
A poorly running engine, dirty injectors, incorrect propeller selection, or maintenance issues may increase fuel usage.
Modern Tohatsu EFI engines rely on multiple sensors and engine management systems. We diagnose electronic faults using professional diagnostic procedures.
Gear oil leaks, worn seals, noisy gears, water intrusion, and shifting concerns are common lower unit issues that require prompt attention.
Don't Ignore These WArning Signs
If your Tohatsu outboard is showing any of these symptoms, professional diagnostics can help prevent expensive repairs later.
⚠️ Cranks But Won't Start
⚠️ Runs Rough
⚠️ Loses Power
⚠️ Displays Warning Alarms
