An engine does not fail suddenly. It drifts, and nobody was measuring.
Every figure that matters about a marine diesel — exhaust temperature, coupling gap, raw water rise, anode wastage — is meaningless as a single reading and decisive as a series. The Engine & Drivetrain Command Kit is the whole cluster bought at once, so that the baseline you set this spring is still there to measure against in four years' time.
What is in the kit
- Marine Diesel Baseline & Trend Log — your manual's figures transcribed once, a commissioning baseline, and sixteen trend entries indexed by engine hours, 26 pages
- Drivetrain Alignment & Shaft Record — all four coupling gaps every session, never averaged into one figure, 24 pages
- Cooling & Exhaust Service Record — raw water temperature rise, exchanger effectiveness and the impeller and anode chronology, 28 pages
Why the three together beat the three apart
A rising exhaust temperature is a cooling question until you check the alignment and find the shaft is dragging. The three documents share one commissioning baseline and one engine-hours axis, so a deviation shows up in whichever register is actually responsible for it — rather than in the one you happened to open.

The rule every document in the kit obeys
Not one published tolerance, clearance, torque or service interval anywhere in 78 pages. Those belong to the maker of your engine and your gearbox, in the revision of the manual that matches your serial number. Each document opens with a reference page where you transcribe your own figures, with the source document and page recorded beside each — and every model measures against that page and nothing else.
What it is not
These documents record and organise. They are not a service manual, not engineering advice, and not prepared by a qualified marine engineer. They reach no conclusion about any engine or any installation.
Bought separately, $291. As a kit, $177 — you keep $114.
