What this sheet is for
Turn the hour meter into a service schedule you can actually read. An oil change is then due at a number on the page, not at some point this season.
Who it is for
Owners of a boat with an inboard or sterndrive engine and an hour meter — yachts, motor cruisers, fishing boats and workboats.
How to use it
- Copy your manufacturer's service schedule into the top block, one job per line, with the interval in hours or months.
- Read the hour meter at the end of every run and write the start, end and hours run.
- Note anything the engine did that it does not usually do — smoke, a drip, an alarm.
- When a job is done, update Last done at and work out Next due at from your interval.
- Keep the finished sheets: buyers and surveyors ask for exactly this.
What is on the sheet
2 pages, in this order:
Page 1
Printed under the title: The engine hour meter read at the end of every run, and the servicing that falls due against those hours — so the next oil change is a number on the page, not a feeling about last summer.
Your manufacturer's schedule, in your hand. The hours at which each job falls due come from your engine manufacturer's schedule, and they differ between engines, fuels and how hard the boat is used. Copy your own schedule into the first block and use it every time. An outboard belongs on the Outboard Motor Service Log; this sheet is for an inboard or sterndrive with an hour meter.

Questions
How is this different from the Boat Maintenance Log?
That sheet is the whole boat — engine, hull, rig and gear — in one running record. This one is only the engine, read against its hour meter, with the service schedule and the hours log next to each other so due dates come off the page.
Why are there no service intervals printed?
Because they are the engine maker's, and a small diesel, a petrol sterndrive and a workboat engine on heavy duty are all different. The Every column is blank so you can fill it from your own handbook.
