"Nothing ruins a day on the water faster than an engine that won't start when you're trying to dock. This one-day course is designed to take the mystery out of your marine diesel and give you real confidence under the hatch. We will cover the core basics: fuel systems, cooling, lubrication, and air, all in plain English, so you understand how everything works together. Most importantly, you will learn a simple, structured process for troubleshooting that you can actually rely on while underway. When a problem pops up out on the water, you will not have to guess or panic. You will have a clear checklist to systematically isolate the issue and figure out your next step. Whether you want to handle your own basic maintenance or just to know what to do when an alarm sounds, you will walk away with practical skills every boat owner needs."
