Part of the Yanmar Operator Manuals.
Air in the fuel lines will keep a Yanmar 6CX(M)-ETE cranking without firing, and the fix starts at the right bleed point in the right order. The factory operator manual for this marine diesel puts that procedure, and every other routine job, into one 58 page PDF, publication 499613-00241.
Inside are the numbers you check before anything goes back together: a 23 liter oil pan, 36 liters of fresh water, fuel injection timing of 12 degrees plus or minus 1, and filter changes at 500 service hours. Sections run from fuel and lube oil selection through first start on a new engine, operation, clutch and reduction gear handling, and periodical service on the fuel, lube, cooling water, and electrical systems.
When the engine sits dead the boat sits with it, so the troubleshooting guide matters: it traces abnormal lube oil pressure, high fresh water temperature, and clutch oil pressure to their causes, with system diagrams to follow the plumbing.
