Service an outboard by hours rather than by dates, and keep the impeller and anode record that decides whether the motor has a long life or a short one.
Owners of outboard-powered boats, tenders and ribs, in salt water and fresh.
2 pages, in this order:
Printed under the title: Hours, servicing and salt-water flushing for an outboard motor. The impeller and the anodes are the two cheap parts whose neglect turns into an expensive one.

A rubber impeller hardens and takes a set long before it stops pumping, and it is usually the last thing to fail before an overheat. Replacement intervals come from your own manual and vary with use, but the point is that it is a cheap part protecting an expensive one.
Long enough for the block to come up to temperature and then run cool, so the salt is actually carried out rather than diluted. Your manual gives a time for your motor and says whether it may be run out of the water — some may not be.

Track battery voltages as a series rather than a single reading, so a bank that is dying is obvious well before it strands you.
Put the autumn lay-up jobs and the spring launch checks on the same page, so what you did in October is in front of you in April.
Every sheet, binder, game and puzzle on Upkeep Papers is free to download, with no email and no account. Making them is not free: each one takes days of research, design and checking, and the site costs money to run. If something here saved you time, you can buy us a coffee. It is entirely optional: nothing is locked, and nothing changes if you don’t.
