What is Marine Engine Diagnostics?

Just as the phrase implies, marine engine diagnostics involves the analysis of the engine using the integrated computer system. A technician will connect to the ECM (Electronic Control Module) using specialized equipment. The software program and computer system used has an adapter that is specific to the engine manufacturer. The connection helps gather crucial data about the history of an engine. By linking into an ECM, a surveyor is able to collect vital information on the engine of your target vessel. In Topping marine engine diagnostics an analysis scan enables the surveyor to verify crucial details like RPM run history of the engine, actual engine hours, current and historic fault codes. This information helps understand how the engine has been operated and how it operates now.

In general, an engine diagnostic will provide beneficial information pertaining to the history of an engine. This data helps you, the buyer, to make a more educated decision when buying a boat. We have a ground-breaking software for inboard powered vessels. Our software can record the actual efficiency of an engine during a sea trial. This helps verify the accuracy of the gauges and collect precise details on the overall efficiency of an engine. It is good to keep in mind that engine diagnostics is an extra option. However, when combined with aquatic studies on gasoline inboard and outboard engines that are ECM equipped, you get a clearer picture on the condition of a boat.
