Our 3 Cyl Universal Engine


This class is designed for both the recreational user of small diesel engines and the professional user of these engines.  Class size is limited to a maximum of 12 students, 6 students working on each engine.

This course is a prerequisite for the 2 day advanced diesel class.

Upon Completion:

You will understand the dynamics of how your marine diesel engine works, all of it's different systems, how those systems interact and all of the different maintenance procedures to keep the engine in tip top running order.

Starting Dates:

The 2019 sessions set up at this time are Friday, March 13 - Sunday, March 15, and Friday, November 20 - Sunday, November 22.  If neither of these dates work, please send us an email - This email address is being protected from spambots.

Getting Started:

  • After you have registered, you will receive an automated email with instructions on where and when the class is being held.
  • The class will be held at our shop location, 11726 Shaffer Place, Unit 606, close to C470 and Ken Caryl Parkway in Littleton, Colorado.
  • We typically handout all course material at the class.

The systems covered will include:  water separators, fuel filters, cooling systems, water pumps, domestic hot water systems, muffler cans, mixing elbows, heat transfer units.  As we are reviewing all of these systems, we have samples that can be taken apart to actually see how the units work ,  


  • The textbook - Marine Diesel Engines:  Maintenance, Troubleshooting, and Repair by Nigel Calder.
  • All tools and safety gear.
  • We will supply coffee & water, pastries for breakfast & pizza or sandwiches for lunch.

General Description:

We have two working marine diesel engines set up on 2 carts (a 2 cyl. Yanmar and a 3 cyl Universal), so we will actually perform all the maintenance tasks on the engines.  These engines are complete with all the filters, switches and pumps found on most marine installations.  The course is suitable for numerous engine makes and models, including Yanmar, Westerbeke, Volvo, Perkins, Nanni, Kubota and more.

The class is a 1 day (9:00 to 4:00) course and will cover the following topics:

  • Principles of Operation
    • A detailed explanation of how 4 stroke gas & diesel engines work.
  • The anatomy of a diesel engine
    • A detailed explanation of the physics of diesel fuel combustion and the timing of that combustion.
  • Electrical starting circuit
    • Taking apart a starting solenoid to determine how it works.
  • Using a multimeter
    • reviewing the differences (and discussing the pros & cons) between an analogue and a digital multimeter.
    • Using a multimeter to measure voltage and connectivity.
    • Using a multimeter to analyze and troubleshoot the engine gauges.
  • The marine engine systems
    • identifying and itemizing the parts of the electrical, fuel & cooling systems for 2 different types of engines.
  • Basic Maintenance and troubleshooting
    • Winterizing the engine
      • Changing the fuel filters (therefore having to bleed the engine).
      • Changing the oil.
      • Checking the antifreeze.
      • Checking and replacing the water pump impeller.
      • Checking and reviewing how to replace the fan belts.
