Marine Engines

Marine Engines

This 3 days course is for sailors who want to be able to maintain, troubleshoot and repair their inboard diesel engine and dinghy outboard engine. You will learn how to properly maintain your engine, including oil change, filter change, impeller change ... but also trouble shoot starting problems, alternator charging, fuel injection, cooling system verification .... This is a very hands on course on real engines.

Course objective: Prepare sailors to maintain, troubleshoot and repair their engines
Pre Course Experience: None
Assumed knowledge: None
Duration: 3 days, 2 days for inboard diesel engine, 1 day for outboard engine
Cost: €325

What will I learn ?

  • Principles of diesel (4 strokes)
  • Principle of outboard (2 strokes – 4 strokes)
  • Parts of engine
  • Electrical systems (solenoid, starter, alternator, batteries…)
  • Fuel systems (fuel pumps, filters, bleeding…)
  • Cooling systems (sea water/fresh water cooling systems)
  • Maintenance (oil, fuel filters, oil change, impeller change, winterizing…)
  • Troubleshooting (starting a motor, smoke analysis, rocker adjustment…)
  • Engine repair

This is a course where you get your hands dirty ! Most sailors have had experience with engine failure (yours truly !) and it usually happens when you need your diesel the most, like when you want to enter a marina for instance. From diesel bugs in the fuel tank to leaking cooling systems or faulty injectors… most skippers have had to get the tool box out and become contortionist to get to the engine compartment to fix diesel engine problems.

Diesel engines (unlike outboards) are very sturdy and if well maintained, will run forever. But the sea environment is very aggressive on marine diesel and care should be taken to ensure proper functioning.

This course will familiarize you with the principle of diesel and combustion engine by which we need to compress air to create heat, inject diesel to create an explosion that pushes a piston down while trying to cool the engine with sea water and fresh water at the same time.

We have at our disposal a marine diesel engine and an outboard, both accessible in our workshop in addition to starter motors, alternators, cooling systems. You will learn how to recognize each part and their functions. The engine can be taken apart to observe the pistons, the injectors, the rocker arms, the heat exchanger, the solenoid and starter motor.

We will teach you how to inspect and clean each part, troubleshoot electrical components like the voltage regulator on the alternator, the solenoid. With a multimeter, you can monitor conductivity and resistance on several parts, check if there is a ground fault …

We will look at the fuel intake system from the tank to the injectors, through each filter and the injector pump to verify that fuel is reaching the combustion chamber.

You will come out of this diesel course with a good understanding of the maintenance and troubleshooting of a basic diesel engine and be able to perform most repairs.

Then we will move to the more capricious outboards with their 2 strokes (mostly), rattling noises, smokes and constant problems that only a Zen Buddhist master can start without loosing his temper.

We will start by looking at the principle of petrol engines (as opposed to diesel) and 2 strokes (as opposed to 4 strokes on an inboard diesel). We will focus on the functioning of the carburetor by dismantling it and look at the jets and how the air/fuel mixture is controlled. Armed with a screw driver we will find that delicate tuning point where the idle position is neither stalling the engine nor making more noise than a 747 taking off.

Moving down the engine, we will dismantle the propeller to expose the “dog clutch” which allows the engine to be in idle, move forward or backward. We have no idea why it is called a “dog clutch” by the way ….
