Mack-Boring Hands-On Diesel Course — Yanmar Marine Diesel

If you own a boat with a diesel engine on it, you know the meaning of reliability and simplicity. But like any piece of equipment, a diesel does require some care and maintenance. What is the best way to learn how to do your own maintenance? I found that taking a hands-on course was an excellent vehicle for learning.

Course Details

Provider
Mack-Boring
Instructor
Larry Berlin
Duration
Three days
Class Size
Limited to ten amateur mechanics
Engine
Yanmar marine diesel (3JH2E — same model as the one in Ken's sailboat)
The instructor, Larry Berlin, was excellent and I would recommend his course to anyone who wants to get started in handling their own routine maintenance. The engine my partner and I worked on was the same model as the one in my sailboat. Can't do much better than that!

What We Covered

Starter & Oil Cooler

Hands-on removal, inspection, and reinstallation of the 3JH2E starter and oil cooler components.

Thermostat Service

Learning the right way — and the wrong way — to service the thermostat. Larry shows us how it is done.

Cylinder Head Re-Torque

14 cylinder head bolts, properly torqued in sequence. Keeping things organized is half the battle.

Starting Her Up

After three days of work, the moment of truth: time to start her up. A $1,000 job done yourself.

Below you will find a few pics I took over the three days of learning. If you have a diesel on your boat, I highly recommend this course.
