Power supply: battery, charging, grounds, connectors, corrosion of contacts
Fuel and cooling systems, performance parameters at different operating modes

TEXA Marine — the foundation of precise diagnostics

We use the professional TEXA Marine system (diagnostic interface + laptop software) with adapters for popular brands.

System capabilities:

Functionality depends on the specific model and ECU

Engine electronic systems: injection, ignition, sensors, ECU
Tests of actuators (pumps, coils, injectors, relays, etc.)
Viewing “live” parameters and graphs (temperature, pressure, RPM, lambda, angles, etc.)
Service functions: service interval resets, calibrations/adaptations (where supported)
Generation of a system condition report for the client

We support the main brands of outboard and inboard engines:

Compatibility is always checked before connection.

When to run diagnostics

Hard starting, unstable idle, loss of power
After long storage, before the start of the season, or before buying equipment
Overheating, increased fuel consumption, smell of gasoline
Errors or signals on the dashboard

How we work
