Marine Engine Diagnostics

What is Marine Engine Diagnostics?

Marine Engine Diagnostics is the analysis of the engine’s built in computer system. This is done by connecting to the engine’s Electronic Control Module (ECM). The computers and software we use has an adapter unique to the engine manufacture to provide valuable information regarding the engines’ history. By connecting into the ECM we can learn valuable information regarding your potential purchase. By doing engine diagnostic scans this enables the surveyor to verify valuable information such as the actual engine hours, the RPM run history so we know how the engines have been operated during their life, current engine fault codes as well as historic fault codes. Engine diagnostics provides valuable information regarding the engine’s history to better enable our customers to make an informed decision before the purchase of the vessel. On inboard powered boats our sophisticated software has the ability to actually record the engines performance during the sea trial. This enables our surveys to verify the helm gauges accuracy and get exact details on the engine’s performance when sea trialing. Engine diagnostics is available as an additional option in conjunction with a marine survey on all gasoline inboard and most outboard engines providing the engines are ECM equipped.

Outboard Engine Diagnostics

Sun Coast Marine Surveying now offers engine diagnostics scans on all outboard and jet ski engines. The diagnostics software connects into the engines electronic control module and eneables our surveyors to veryify engine hours, RPM run history, fault codes and in some cases service history. This valuable information assists the buyer in making an informed decision when purchasing a vessel with outboards or a jet ski. This is an optional service offered only in conjunction with a marine survey on a vessel.

Over the past decade we’ve collected a wealth of knowledge from the marine service technicians and dealerships we support. This gave our engineers quite a wish list of features to consider. Thanks to your input, Diacom has been made more intuitive, more streamlined, and more discoverable, so you can complete all of your work in less time.

Internet Connectivity

Chances are the Internet has already changed the way you interact with your customers and suppliers. Now it will change the way you troubleshoot. Diacom was designed to be Internet “aware” and provides features that allow the easy Diacom Kit Configurations exchange of data with other parties. Diacom can also convert engine data into formats easily read by other popular PC programs such as Microsoft Excel and Access.

Big Screen, Huge Advantage

Notebook screens have never been bigger and brighter. Diacom takes full advantage of your PC’s expansive display and shows you the “Big Picture” of what’s happening.

The Electronic Information Age
