These are real pages from the book. The table of contents is the full one: 9 parts and 61 topics.
You're on your round near the purifiers, and the second engineer asks you to walk him through the fuel line, from the bunker tank to the injector. You've followed that pipe a hundred times. Out loud, the order slips.
Last night you went over it in the manual: settling tanks, service tanks, booster pump, heater, viscosity control, all buried in long paragraphs. Eleven components in a row of sentences, and no line connecting them.
In the book, the fuel route is one page: storage → transfer pump → settling → purifier → service → booster → heater → viscosity → filter → engine → return. Drawn in brown, one arrow after another, the way the pipe actually runs.
Lube oil, jacket water, sea water cooling, starting air and the oily water separator get the same treatment: one page each, same route, same order.
Next time someone asks, you picture the page and trace it. You understand it, and you say it without going back to the manual.
The engine room map, the diesel engine, fuel oil, lube oil and cooling water, starting air, pumps and valves, boilers and refrigeration, electrical, pollution prevention and watchstanding: 65 pages, all illustrated
Think of it this way:
You're on watch and the lube oil pressure at the engine inlet starts to drop. The engineer is on the phone, waiting for you to tell him what you see.
You studied the lube oil page the night before, so you picture the whole loop in yellow: sump, pump, cooler, filter, bearings, the purifier in a side loop and the gauge at the engine inlet. You tell him what you see, in order.
Same with the fuel route, the jacket water loop, starting air, the oily water separator and the refrigeration cycle: each one on its own page, always in the same order.
QMED Engine Room Illustrated is 9 parts and 61 topics, all drawn, and it ends with the 10 most common mix-ups and how to read a USCG multiple-choice question.
What you see drawn, you don't have to memorize.
Read any page in one pass (tank → pump → filter → cooler → user), see the whole engine room on one map, and know how the QMED ratings, the USCG exam and its units work.
4-stroke and 2-stroke cycles, compression ignition, engine parts, fuel injection, turbocharger and scavenge air, governor and overspeed trip, exhaust temperatures and crankcase safety.
The fuel route from bunker tank to injector, grades and viscosity, settling and service tanks, purifier vs clarifier, purifier start-up and shutdown, filters and bunkering.
The lube oil route, what lube oil does, low lube oil pressure checked in order, the jacket water loop, sea water cooling, central cooling and high jacket water temperature.
The starting air route, compressor stages, air receivers, centrifugal vs positive displacement pumps, priming, packing vs mechanical seals, valve types and bilge vs ballast.
Auxiliary boiler and economizer, the gauge glass, water treatment and blowdown, steam traps and the hot well, the refrigeration cycle, superheat and subcooling, and EPA refrigerant rules.
Ohm's law and power, AC generators and paralleling, the main switchboard, emergency power, motors and insulation testing, and lockout/tagout.
The oily water separator and the 15 ppm rule, the Oil Record Book, other discharges, engine room fire, the fixed CO2 system, remote shut-offs and enclosed space entry.
The oiler's round in order, taking over the watch, when to call the engineer, steering gear checks, the 10 most common mix-ups and how to read a USCG multiple-choice question.
At the end of the book: Exam-style questions with answers, the 10 most common mix-ups and how to read a USCG multiple-choice question.
Exam-style multiple-choice questions by system, each with the answer explained and the page of the book to go back to, so you find out what you really know before exam day.
The most common mix-ups (2-stroke vs 4-stroke, centrifugal vs positive displacement, purifier vs clarifier, bilge vs ballast) on printable one-glance cards to review between watches.

Yes. It doesn't explain what a wrench is: it starts from the engine room you already know and draws each system as a route. It covers the general engine topics the QMED ratings share (diesel, fuel, lube oil, cooling, starting air, pumps and valves, boilers, refrigeration, electrical, pollution prevention and watchstanding), with the most depth for Oiler and Junior Engineer. If you're going for Electrician or Refrigerating Engineer, it gives you the base, not the full specialty.
From the USCG National Maritime Center QMED exam topics and the endorsement rules in 46 CFR Part 12, the oil pollution rules in 33 CFR Parts 151 and 155 (MARPOL Annex I), and 46 CFR Subchapters F, H and J. Every rule value on a page (the 15 ppm limit, the Oil Record Book, the fixed CO2 system) carries its CFR or MARPOL reference, so you can check it against the current text on eCFR.
No. It's an independent study book. It isn't published, approved or endorsed by the U.S. Coast Guard, the NMC or any approved school, and it doesn't give you a certificate, sea time or course credit.
No. It's a review tool to use alongside your course, your sea time and what the engineers teach you on board.
No. They're exam-style questions written for this book, each with the answer explained. They aren't official USCG questions.
As a PDF by email, at the address you enter at checkout. The 2 bonus books come in the same email.
No. It's a one-time payment. No subscription.
It's a PDF, not a printed book. It prints fine at home or at a print shop, best in color since every fluid has its own color, so you can keep a copy in your locker on board.
You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
No more rereading pages that don't stick.
The fuel route: you see it drawn, and that's it.
You walk into the exam knowing where everything is.
Drawings make studying faster.
