I drove down to the coast this week to join Lori and Mike on Trident to work on some boat projects. We sat through a day-long, hands-on class for “Marine Diesel Engine Introduction and Maintenance” which was delivered on-board Trident. I learned a tremendous amount, and now feel like I have a basic understanding of how a diesel engine works, and how some maintenance can be done. At night I dreamt of primary fuel filters, lift pumps, fuel pumps, engine fuel filters, injector pumps, injectors, oil extractors, heat exchangers, impellers, strainers, shut-off valves, stop-cocks, oh, my!
Today, after the lecture part of the class, Lori and Mike performed the following maintenance to Trident: primary fuel filter change, engine fuel filter change, impeller change, oil change, oil filter change, belt tension check, transmission fluid check, heat exchanger coolant check, raw water strainer cleaning). Nine hours of learning and doing. I’m looking forward to opening up Nirvana and seeing if I can identify all the components on her 3 cylinder, 30 HP Yanmar diesel.
Why do they put such big engines in such small places?
The engine and generator are inside this compartment, comically called the engine “room.” There is actually a guy (the teacher) sitting on the generator inside this compartment, pointing to components on the engine behind it.
Lori is changing the primary fuel filter here, reaching through the aft access door to the engine “room.”
