Each engine has an hours reading: tap the engine on your boat’s screen to see it. Ballast uses it to fill in log entries and to schedule to-dos that repeat by hours.
Choose an engine for an entry and Ballast fills in its current hours. If the meter says otherwise, type what it says. For work in the past, choose the engine first, then correct the hours, since choosing an engine fills them in again.
An entry with higher hours than the engine moves the engine up. One with lower hours leaves the engine alone, so logging a service from years ago doesn’t wind the engine back.
Turn on Retired instead of deleting it. It keeps its history but isn’t offered for new entries or to-dos.
Still stuck? Hail us.
