What this sheet is for
Service a marine engine by hours, and keep the impeller and anode record that matters more than almost anything else on a boat.
Who it is for
Owners of outboard, inboard and sterndrive boats, and anyone laying a boat up for winter.
How to use it
- Record part numbers for the impeller, filters and anodes once.
- Log engine hours at every service.
- Replace the impeller on schedule — it is cheap and its failure is not.
- Work through lay-up and launch lists at each end of the season.
What is on the sheet
The layout is fixed at a size that fits both A4 and US Letter, so the A4 and Letter files are visually identical and print at full size on either. Rows are set at a height that an adult can actually write a date and a few words into with a pen — most printable tables are built in a word processor and never tested with one.
Questions
Why track hours rather than dates?
Marine engines are specified in running hours, and a boat used heavily for three months may need more servicing than one used lightly all year. Hours are the meaningful unit.
