Marine Engine Diagnostics

What is Marine Engine Diagnostics? 

Marine engine diagnostics is the analysis of the engine’s built in computer system (sometimes referred to as the engine’s central processing unit – CPU, engine management module – EMM or the engine control unit – ECU). This is done by plugging a special processor into the ECU of the engine that connects to a small computer. The processeor communicates with the onboard ECU and tells the technician valuable information about the engine which includes: The engine’s model number, the engine’s serial number, actual engine hours, the engine’s RPM history profile, the engine’s running temperature profile, current and stored fault codes, and a data parameter summary. Engine diagnostics is essential to know and understand the engine’s history, current issues, verify hours, and helps to understand the true overall condition of the engine. Computerized marine engine diagnostics saves hours of labor time (and money) on trouble shooting the engine and lets the technician know exactly what the problems are.

We offer this service and use the latest in marine engine diagnostic technology. It is a simple and easy service to perform. We can come to the vessel’s location to perform the service. The vessel can be in or out of the water for this service to be performed. Better diagnostic analysis of the engine can be conducted if the engine can be started and ran with a proper cooling water source.

Currently the engines that we can perform computerized diagnostics on are:

  • Yamaha four stroke outboard engines
  • Mercury / Mariner four stroke outboard engines
  • Johnson and Evinrude four stroke FICHT and E-TEC engines
  • MerCruiser four stroke inboard gasoline engines
  • Yamaha personal watercraft engines

A written report with the complete engine diagnostics information and results is included with the service and would be sent to you within 24 hours after the diagnostics is performed. The report can be sent to your email address on a PDF document.
