The diesel engine is the beating heart of your vessel, whether you cruise under power or sail. Arguably, a good running engine is your most important single piece of safety gear. Diesel engines are economical, long-lived and reliable, yet there are a number of ways in which they can fail. This seeming contradiction brings us to the distinction that has shaped the “Online Marine Diesel Maintenance & Troubleshooting” course.

The internal workings of a diesel engine rarely fail—pistons, valves, shafts—and even if they were to fail, there is almost nothing boat owner could do about it except to call a repair shop. That’s why this course focuses solely on components that are 1) likely to go wrong and 2) repairable or preventable by a boat owner. Course segments address how to troubleshoot fuel, electrical, cooling and corrosion issues, etc., and describe how savvy maintenance can prevent these ancillary components from failing in the first place.

The course is about being independent. It is designed to impart the mechanical know-how that participants need to venture past the sight of land or to destinations beyond the range of SeaTow. And even if you intend to do your boating close to home and plan to hire technicians for maintenance and repairs, this course has value.

While most marine professionals are honest and competent, occasionally you may find yourself dealing with an exception. The 11 segments of this course will impart enough knowledge to ask your mechanic the right questions and evaluate the answers.

In short, “Online Marine Diesel Maintenance & Troubleshooting” is a twofold self-defense course. It imparts the knowledge to deal with the problems most likely to occur underway and to detect misinformation in the repair marketplace. This course may very well pay for itself many times over.
